An Effective Preprocessing Algorithm for Model Building in Collaborative Filtering based Recommender System 
by Srikanth T, M. Shashi
Abstract: Recommender systems suggest interesting items for online users based on the ratings expressed by them for the other items maintained globally as the rating matrix. The rating matrix is often sparse and very huge due to large number of users expressing their ratings only for a few items among the large number of alternatives. Sparsity and scalability are the challenging issues to achieve accurate predictions in recommender systems. This paper focuses on model building approach to collaborative filtering-based recommender systems using low rank matrix approximation algorithms for achieving scalability and accuracy while dealing with sparse rating matrices. A novel preprocessing methodology is proposed to counter data sparsity problem by transforming the sparse rating matrix denser before extracting latent factors to appropriately characterise the users and items in low dimensional space. The quality of predictions made either directly or indirectly through user clustering were investigated and found to be competitive with the existing collaborative filtering methods in terms of reduced MAE and increased NDCG values on bench mark datasets.

by Appavu Alias Balamurugan, P.K.A. Chitra, S. Geetha
Abstract: Many multi label problem transformation (PT) and algorithm
adaptation (AA) methods need to be explored to get good candidate for
avifaunal occupancy modelling. This research contrasted eight commonly used
state-of-the-art PT and AA multi label methods. The data was created by
collecting January 2014December 2014 records from e-bird repository for the
study area Madurai district, south eastern Tamil Nadu. The analysis shows that
classifier chain (CC) and multi label naive Bayes (MLNB) are the good
aspirants for avifauna data. The MLNB did best with 0.019 hamming loss and
90% average precision. To the best of our knowledge this is the first time to use
MLNB for avifaunal data and the results of multi label naive Bayes concludes
that out of 143 species observed, six species had high occurrence rate and 68
species had low occurrence rate.

CBRec: a book recommendation system for
children using the matrix factorisation and
content-based filtering approaches
by Yiu-Kai Ng
Abstract: Promoting good reading habits among children is essential, given
the enormous influence of reading on students development as learners and
members of the society. Unfortunately, very few (children) websites or online
applications recommend books to children, even though they can play a
significant role in encouraging children to read. Given that a few popular
book websites suggest books to children based on the popularity of books or
rankings on books, they are not customised/personalised for each individual
user and likely recommend books that users do not want or like. We have
integrated the matrix factorisation approach and the content-based approach,
in addition to predicting the grade levels of books, to recommend books for
children. Recent research works have demonstrated that a hybrid approach,
which combines different filtering approaches, is more effective in making
recommendations. Conducted empirical study has verified the effectiveness of
our proposed children book recommendation system.

by M. Pradeepa Sivaramakrishnan, C. Deisy
Abstract: In this research work, multi-word target related terms are extracted
automatically from the customer reviews for sentiment analysis. We used LIDF
measure and have proposed a novel measure called, TCumass in iterative
multi-word target (IMWT) bootstrapping algorithm. In addition, part-of-speech
pattern recognition (PPR) algorithm has been proposed to identify the
appropriate target and emotional words from multi-word target related terms.
This article aims to bring out both implicit and explicit targets with their
corresponding polarities in an unsupervised manner. We proposed two models
namely, MWTB without PPR and MWTB with PPR. Thus, the present research
illustrates the comparison between the proposed works and the existing
multi-aspect bootstrapping (MAB) algorithm. The experiment has been done
based on different data sets and thereafter the performance evaluated using
different measures. From this study, the result expounds that MWTB with PPR
model performs well, having achieved the precise targets and emotional words.

by Alexander A. S. Gunawan, Heri Prasetyo, Indah Werdiningsih, Janson Hendryli
Abstract: In our research, we would like to exploit crowdsourced photos from
social media to create low-cost fire disaster sensors. The main problem is to
analyse how hazy the environment looks like. Therefore, we provide a brief
survey of methods dealing with visibility level of hazy images. The methods
are divided into two categories: single-image approach and learning-based
approach. The survey begins with discussing single image approach. This
approach is represented by visibility metric based on contrast-to-noise ratio
(CNR) and similarity index between hazy image and its dehazing image. This
is followed by a survey of learning-based approach using two contrast
approaches that is: 1) based on theoretical foundation of transmission light,
combining with the depth image using new deep learning method; 2) based on
black-box method by employing convolutional neural networks (CNN) on hazy
images.

Application of a hybrid data mining model to identify the main predictive factors influencing hospital length of stay
by Ahmed Belderrar, Abdeldjebar Hazzab
Abstract: Length of hospital stay is one of the most appropriate measures that can be used for management of hospital resources and assistant of hospital admissions. The main predictive factors associated with the length of stay are critical requirements and should be identified to build a reliable prediction model for hospital stays. A hybrid integration approach consisting of fuzzy radial basis function neural network and hierarchical genetic algorithms was proposed. The proposed approach was applied on a data set collected from a variety of intensive care units. We achieved an acceptable forecast accuracy level with more than 80.50%. We found 14 common predictive factors. Most notably, we consistently found that the demographic characteristics, hospital features, medical events and comorbidities strongly correlates to the length of stay. The proposed approach can be used as an effective tool for healthcare providers and can be extended to other hospital predictions.

Genetic Algorithm based Intelligent Multiagent Architecture for Extracting Information from Hidden Web Databases
by Weslin D, T. Joshva Devadas
Abstract: Though there are enormous amount of information available in the
web, only very small portion of the available information is visible to the users.
Due to the non-visibility of huge information, the traditional search engines
cannot index or access all information present in the web. The main challenge
in the mining of the relevant information from a huge hidden web database is to
identify the entry points to access the hidden web databases. The existing web
crawlers cannot retrieve all information from the hidden web databases. To
retrieve all the relevant information from the hidden web, this paper proposes
an architecture that uses genetic algorithm and intelligent agents for accessing
hidden web databases. The proposed architecture is termed as genetic algorithm
based intelligent multi-agent system (GABIAS). The experimental results show
that the proposed architecture provides better precision and recall than the
existing web crawlers.

Efficient Clustering Technique for K-Anonymization with Aid of Optimal KFCM
by Chitra Ganabathi G., P. Uma Maheswari
Abstract: The k-anonymity model is a simple and practical approach for data
privacy preservation. To minimise the information loss due to anonymisation, it
is crucial to group similar data together and then anonymises each group
individually. So that in this paper proposes a novel clustering method for
conducting the k-anonymity model effectively. The clustering will be done by
an optimal kernel based fuzzy c-means clustering algorithm (KFCM). In
KFCM, the original Euclidean distance in the FCM is replaced by a
kernel-induced distance. Here the objective function of the kernel fuzzy
c-means clustering algorithm is optimised with the help of modified grey wolf
optimisation algorithm (MGWO). Based on that, the collected data is grouped
in an effective manner. The performance of the proposed technique is evaluated
by means of information loss, time taken to group the available data. The
proposed technique will be implemented in the working platform of MATLAB.

A Novel Attribute Based Dynamic Clustering with Schedule Based Rotation Method (ADC-SBR) for Outlier Detection
by Karthikeyan .G, P. Balasubramanie
Abstract: Detection of outliers in bank transactions has gained popularity in
the recent years. The existing outlier detection techniques are unable to process
the high volume of data. Hence, to address this issue, an efficient attribute
based dynamic clustering-schedule based rotation (ADC-SBR) method is
proposed. The similarity between transactions within a cluster is estimated
using Jaccard coefficient based labelling approach and the optimal cluster head
is chosen by the similarity-based cluster head selection (SbCHS) method.
The outlier detection is performed in two levels. The node level outlier
detection is performed using linear regression model and the cluster level
outlier detection is performed by deviation based ranking. An own dataset with
bank transactions is used for the experimental analysis. The suggested method
is implemented in Apache Spark and is compared with existing algorithms for
the metrics. The comparison results prove that the proposed method is optimal
for all metrics than existing algorithms.

Mining Multilingual and Multiscript Twitter Data: Unleashing the Language and Script Barrier
by Bidhan Sarkar, Nilanjan Sinhababu, Manob Roy, Pijush Kanti Dutta Pramanik, Prasenjit Choudhury
Abstract: Micro-blogging sites like Twitter have become an opinion hub
where views on diverse topics are expressed. Interpreting, comprehending and
analysing this emotion-rich information can unearth many valuable insights.
The job is trivial if the tweets are in English. But lately, increase in native
languages for communication has imposed a great challenge in social media
mining. Things become more complicated when people use Roman scripts to
write non-English languages. India, being a country with a diverse collection of
scripts and languages, encounters the problem severely. We have developed a
system that automatically identifies and classifies native tweets, irrespective of
the script used. Converting all tweets to English, we get rid of the script vs
language problem. The new approach we formulated consists of Script
Identification, Language analysis, and Clustered mining. Considering English
and the top two Indian languages, we found that the proposed framework gives
better precision than the prevailing approaches.

An Automated Ontology Learning for benchmarking classifier models through Gain-Based Relative-Non-Redundant (GBRNR) Feature Selection : A case-study with Erythemato
by S. Sivasankari, Shomona Gracia Jacob
Abstract: Erythemato-squamous disease (ESD) is one of the complex diseases
in the dermatology field, the diagnosis of which is challenging, due to common
morphological features and often leads to inconsistent results. Besides,
diagnosis has been done on the basis of inculcated visible symptoms pertinent
with the expertise of the physician. Hence, ontology construction for prediction
of Erythemato-squamous disease through data mining techniques was believed
to yield a clear representation of the relationships between the disease,
symptoms and course of treatment. However, the classification accuracy
required to be high in order to obtain a precise ontology. This required
identifying the correct set of optimal features required to predict ESD. This
paper proposes the Gain based Relative-Non-Redundant Attribute selection
approach for diagnosis of ESD. This methodology yielded 98.1% classification
accuracy with Adaboost algorithm that executed J48 as the base classifier. The
feature selection approach revealed an optimal feature set comprising of 19
selected features.

by Sekar K., Mokkala Padmavathamma
Abstract: This paper proposes a privacy preserving-aware-based approach
over Big data in clouds using GSA and MapReduce framework. It consists of
two modules such as; MapReduce module and evaluation module. In MR
module, convolution process is applied to the dataset and creates a new kernel
matrix. The convolution process is correctly done; the utility and privacy
information of the data is well secured. Once the convolution process is over,
the privacy-persevering framework over big data in cloud systems is performed
based on the evaluation module. In Evaluation module, the neural-network is
trained based on the Gravitational Search Algorithm with Scaled conjugate
gradient (GSA-SCG) algorithm which is improving the utility of the privacy
data. Finally, the reduced privacy datas are stored in the service provider
(CSP). The MapReduce framework is to ensure the private data, which is in
charge for anonymising original data sets as per privacy requirements.

An Utility Based Approach for Business Intelligence to Discover Beneficial Itemsets With or Without Negative Profit in Retail Business Industry
by C. SIVAMATHI, S. Vijayarani
Abstract: Utility mining is defined as discovery of high utility itemsets from the large databases. It can be applied in business Intelligence for business decision-making such as arranging products in shelf, catalogue design, customer segmentation, cross-selling etc. In this work a novel algorithm MAHUIM (matrix approach for high utility itemset mining) is proposed to reveal high utility itemsets from a transaction database. The proposed algorithm uses dynamic matrix structure. The algorithm scans the database only once and does not generate candidate itemsets. The algorithm calculates minimum threshold value automatically, without seeking from the user. The proposed algorithm is compared with the existing algorithms like HUI-Miner, D2HUP and EFIM. For handling negative utility values, MANHUIM algorithm is proposed and this is compared with HUINIV. For performance analysis, four benchmark datasets like Connect, Foodmart, Chess and Mushroom are used. The result shows that the proposed algorithms are efficient than the existing ones.

Automated Optimal Test Data Generation for OCL Specification Using Harmony Search Algorithm
by A. Jali
Abstract: Exploring software testing possibilities at an early software life cycle is increasingly necessary to avoid the propagation of defects to the subsequent phases. This requirement demands technique that can generate automated test cases at the initial phases of software development. Thus, we propose a novel framework for automated test data generation using formal specifications written in object constraint language (OCL). We also defined a novel fitness function named exit-predicate-wise branch coverage (EPWBC) to evaluate the generated test data. Another focus of the proposed approach is to optimise the test case generation process by applying, harmony search (HS) algorithm. The experimental results indicate that the proposed framework outperforms the other OCL-based test case generation techniques. Furthermore, it has been inferred that OCL based testing adopting HS algorithm forms an excellent combination to produce more test coverage and an optimal test suite thereby improving the quality of a system.

Unsupervised Key Frame Selection using Information Theory and Color Histogram Difference
by Janya Sainui, Masashi Sugiyama
Abstract: Key frame selection is one of the important research issues in video content analysis, as it helps effective video browsing and retrieval as well as efficient storage. Key frames would typically be as different from each other as possible but, at the same time, cover the entire content of the video. However, the existing methods still lose some meaningful frames due to an inaccurate evaluation of the differences between frames. To address this issue, in this paper, we propose a novel method of key frame selection which incorporates an information theoretic measure, called quadratic mutual information (QMI), with the colour histogram difference. Here, these two criteria are used to produce an appropriate frame difference measure. Through the experiments, we demonstrate that the proposed key frame selection method generates a more coverage of the entire video content with minimum redundancy of key frames compared with the competing approaches.

Building Acoustic Model for Phoneme Recognition using PSO-DBN
by B.R. Laxmi Sree, M.S. Vijaya
Abstract: Deep neural networks has shown its power in generous classification problems including speech recognition. This paper proposes to enhance the power of deep belief network (DBN) further by pre-training the neural network using particle swarm optimisation (PSO). The objective of this work is to build an efficient acoustic model with deep belief networks for phoneme recognition with much better computational complexity. The result of using PSO for pre-training the network drastically reduces the training time of DBN and also decreases the Phoneme error rate (PER) of the acoustic model built to classify the phonemes. Three variations of PSO namely, the basic PSO, second generation PSO (SGPSO) and the New model PSO (NMPSO) are applied in pre-training the DBN to analyse their performance on phoneme classification. It is observed that the basic PSO is performing comparably better to other PSOs considered in this work, most of the time.

Efficient search for top-k discords in streaming time series
by Giao Bui Cong, Duong Tuan Anh
Abstract: The problem of anomaly detection in streaming time series has received much attention recently. The problem addresses finding the most anomalous subsequence (discord) over a time-series stream, which might arrive at high speed. The fact that finding top-k discords is more useful than finding the most unusual subsequence since users might make a choice among the top-k discords instead of choosing only one. Hence, an efficient method of search for top-k discords in streaming time series is proposed in the paper. The method uses a lower bound threshold, a lower bounding technique on a common dimensionality reduction transform, and a state-of-the-art technique of the distance computation between two time-series subsequences to prune off unnecessary distance calculations. The three techniques are arranged in a cascading fashion to speed up the performance of the method. Furthermore, the proposed method can return a set of top-k discords on the fly. The experimental results show that the proposed method can acquire quality discords nearly identical to those obtained by HOT SAX, a well-known method of anomaly detection. Remarkably, our proposed method demonstrates a fast response in handling time-series streams at high speed.
Keywords: anomaly detection; discord; streaming time series.

The non-proprietary software revolution paved the way for illustrious evolution of tools like Weka, rapid miner, orange and R. Traditional data mining techniques hardly adapts to the requirements of rapid data analysis. The data stream processing algorithms that handle multitude of data endow with greater challenge in real time. Big data mining requires further improvisation in traditional tools to address the challenges of Massive data processing. This paper highlights the importance of data stream mining and explores two important open source frameworks, namely massive online analysis (MOA) and scalable advanced massive online analysis (SAMOA). The implications of both the tools augurs well for further deliberations in big data research community. Business information system (BIS) models can reach unprecedented heights with the proliferation of these business analytics tools.

A novel dynamic approach to identifying suspicious customers in money transactions
by Abdul Khalique Shaikh, Amril Nazir
Abstract: Money laundering activity causes a negative impact on the development of the national economy. Anti-money laundering (AML) solutions within financial institutions facilitate to control it in a suitable way. However, one of the fundamental challenges in AML solution is to identify real suspicious transactions. To identify these types of transactions, existing research uses pre-defined rules and statistical approaches that help to detect the suspicious transactions. However, due to the fixed and predetermined rules, it is highly probable that a normal customer can be identified as suspicious customers. To overcome the above limitations, a novel dynamic approach to identifying suspicious customers in money transactions is proposed that is based on dynamic analysis of customer profile features to identify suspicious transactions. The experiment has been executed with real bank customers and their transactions data and the results of the experiment provide promising outcomes in terms of accuracy.
Keywords: AML; anti-money laundering; suspicious transactions; money transaction; dynamic AML analysis; data analysis.

Anomaly detection for elderly home care
by Kurnianingsih Kurnianingsih, Lukito Edi Nugroho, Widyawan Widyawan, Lutfan Lazuardi, Anton Satria Prabuwono, Mahardhika Pratama
Abstract: In this paper, we propose a model for detecting anomalies in elderly home care. Two scenarios are investigated in detecting anomalies: 1) the elderly person's vital signs and their surrounding environment; 2) the mobility patterns of the elderly. We evaluated our proposed model by employing the isolation forest which detects anomalies using an isolation approach on a random forest of decision trees. We compare isolation forest on unlabeled data with statistical methods on labelled data. Subsequently, to show the reliability of the isolation concept, we compare it with a distance measure concept. The experiment shows that isolation forest has higher detection accuracy and lower error prediction for two attributes in the first scenario: skin temperature and heart rate, whereas, in the second scenario, multi-covariance determinant has a slightly better accuracy compared to isolation forest (3.9% difference in accuracy) and has a small number of prediction errors compared to isolation forest.

Grey-Wolf Optimizer Based Feature Selection for Feature-Level Multi-Focus Image Fusion
by Sujatha K, D. Shalini Punithavathani, J. Janet, S. Venkatalakshmi
Abstract: This paper proposes optimal ensemble-individual-features (OEIF) for multi-focus image fusion through combining the decision information of individual features. This proposed system consists of three stages. In the first stage, the different types of features such as spatial, texture and frequency are extracted from every block on input blurred images. In the second step, grey wolf optimiser (GWO)-based features validation method is proposed to find suitable features from source images. This method is based on an iterative process, in which each individual represents a candidate solution for validating/invalidating the features. In the final step, the ensemble decision based on optimal individual features is utilised to fuse blurred images. We prove that OEIF method is better in comparison to the noisy feature-based individual pixel-level and the feature-level fusion methods with different multi-focus images and it reveals that OGWO-based proposed method performs better visual quality than other methods.

Online Products Recommendation System using Genetic Kernel Fuzzy C-Means and Probabilistic Neural Network
by Manohar E, D. Shalini Punithavathani
Abstract: The purchaser's review plays a significant role in choosing the purchasing activities for online shopping as a customer desires to obtain the opinion of other purchasers by observing their opinion through online products. However, most appropriate product selection from the best website is a challenging problem for online users. Accordingly, this paper proposes a hybrid recommendation system for identifying customer preferences and recommending the most appropriate product. To do this, first the dataset is collected and prepared in the pre-processing step. Genetic kernel fuzzy C-means (GAKFCM) is used for usage cluster formation after the pre-processing step. The different features are extracted from each cluster-based user interest level. The user interest levels are used as features for classifier to extract user knowledge discovery. Based upon the user interest level, the product recommendation is done using probabilistic neural network (PNN). The simulation results show high precision rate which clearly indicates that the proposed method is very useful and appealing.

Hybridising Neural Network and Pattern Matching under Dynamic Time Warping for Time Series Prediction
by Thanh Son Nguyen
Abstract: Pattern matching-based forecasting models are attractive due to their simplicity and the ability to predict complex nonlinear behaviours. Euclidean measure is the most commonly used metric for pattern matching in time series. However, its weakness is that it is sensitive to distortion in time axis; so, this can influence on forecasting results. The dynamic time warping (DTW) measure is introduced as a solution to the weakness of Euclidean distance metric. In addition, artificial neural networks (ANNs) have been widely used in the time series forecasting. They have been used to capture the complex relationships with a variety of patterns. In this work, we propose an improved hybrid method which is an affine combination of neural network model and DTW-based pattern matching model for time series prediction. This method can take full advantage of the individual strengths of the two models to create a more effective approach for time series prediction. Experimental results show that our proposed method outperforms neural network model and DTW-based pattern matching method used separately in time series prediction.

REFERS: Refined & Effective Fuzzy E-commerce Recommendation System
by Sankar Pariserum Perumal, Ganapathy Sannasi, Kannan Arputharaj
Abstract: Online shopping culture is gaining traction globally and some of the biggest beneficiaries of this e-commerce shift are Amazon, eBay, etc. Recommendation systems guide online users in a personalised manner to choose what they want and their interest on each product present in the catalogue list. In such a scenario, the existing systems need complete information for making recommendations, which is not always possible in real applications. Therefore, a novel refined and effective fuzzy e-commerce recommendation system has been proposed in this paper that combines the benefits of difference in importance within the rating factors by a single user and new similarity measure approach that aims at improved recommendation list to the e-commerce user. The proposed methodology has been implemented using a new similarity measure on experimental datasets and the refined scores for such e-commerce website-based unlocked mobile phones are compared in this work against classic similarity measures.

Decision tree classifier for university single rate tuition fee system
by Taufik F. Abidin, Samsul Rizal
Abstract: The regulation about single rate tuition fee for undergraduate study at state universities in Indonesia was enacted in 2013. The tuition fee is calculated based on the needs of each academic program and the regional cost index. The fee is grouped into several categories and set differently for each university. For Syiah Kuala University, located in Banda Aceh, Indonesia, the tuition fee is grouped into five different categories. This paper describes the construction of J48 decision tree classifier and evaluates its performance during training and testing phases when compared to ID3 and Naive Bayes classifiers to determine the category. The results show that the J48 decision tree classifier outperforms the other two classifiers in both phases. In the training phase, the F-measure and ROC for the J48 decision tree classifier are 0.889 and 0.973, respectively, and in the testing phase, the F-measure and ROC are 0.911 and 0.987, respectively.

Using Diverse Set of Features to Design a Content-Based Video Retrieval System Optimized by Gravitational Search Algorithm
by S. Padmakala, Ganapathy Sankar Anandha Mala, K.M. Anandkumar
Abstract: This paper explains about the content based video retrieval approach (CBVR) using four varieties of features and 12 distance measurements, which is optimized by gravitational search algorithm (GSA). Initially, CBVR technique extracts five kinds of features such as color, texture, shape, image and audio features that belong to each frame. Consequently, it emerges particular distance measurements for every sort of features to compute the similarity between query frame and remaining in the database frame. In this paper, we have used GSA to find the nearly optimal combination between the features and their respective similarity measurements. At last, from the video database, the query based videos are recovered. For experimentation, here we used two types of databases such as sports video and UCF sports action datasets. The experimental results demonstrate that the proposed CBVR method shows better performance when contrasted with other existing methods.

Discrete Weibull regression for modeling football outcomes
by Alessandro Barbiero
Abstract: We propose the use of the discrete Weibull distribution for modeling football match results, as an alternative to existing Poisson and generalized Poisson models. The number of goals scored by the two teams playing a football match are regarded as a pairwise observation and are modelled first through two independent discrete Weibull variables, and then through two dependent discrete Weibull variables, using a copula approach that accommodates non-null correlation. The parameters of the bivariate discrete Weibull distributions are assumed to depend on covariates such as the attack and defense abilities of the two teams and the 'home effect'. Several discrete Weibull regression models are proposed and then applied to the 2015-2016 Italian Serie A. Even if the interpretation of parameters is less immediate than in the case of bivariate Poisson models, nevertheless these models represent a suitable alternative, which can be applied also in other fields than sport data analysis.

Link prediction in multilayer networks
by Deepak Malik, Anurag Singh
Abstract: Link prediction has gained popularity in recent years in large networks. Researchers have proposed various methods for finding the missing links. These methods include common neighbour, Jaccard coefficient, etc. based on the proximity of the nodes. These methods have limitations as they treat all common nodes equal from a pair of nodes. A new method is proposed, common neighbours common neighbour (CNCN). Its performance is better than the existing methods in a single layer network. These methods are based on the topological features of the network. The proposed method finds the different behaviour of common nodes for a pair of nodes. The link prediction is also useful in the multiplex networks. The link predictions in the multiplex networks are more useful than the single layer network as several layers may give more information about a node than the single layer network. Two methods are proposed using dynamic and static weights.

by Balavivekanandhan A
Abstract: The primary objective of my research is to design and develop semantic annotation and retrieval model for e-learning document. In training phase, the documents from different domains are taken and the informative words from each document are obtained based on balanced mutual information and frequency of contents in each document. We then use the informative words to identify the superordinates and the objects. The superordinates, the informative words and the objects from each document will give the relation and properties of each document. The relation and properties of each document are then used to cluster the documents. In the testing phase, we give a query or a document as input to the system to retrieve the relevant documents. If a document is given as input, the relation and properties of that document are first identified and it is used to retrieve the relevant documents.

Stability analysis of feature ranking techniques in the presence of noise: a comparative study
by Iman Ramezani, Mojtaba Khorram Niaki, Milad Dehghani, Mostafa Rezapour
Abstract: Noisy data is one of the common problems associated with real-world data, and may affects the performance of the data models, consequent decisions and the performance of feature ranking techniques. In this paper, we show how stability performance can be changed if different feature ranking methods against attribute noise and class noise are used. We consider Kendalls Tau rank correlation and Spearman rank correlation to evaluate various feature ranking methods stability, and quantify the degree of agreement between ordered lists of features created by a filter on a clean dataset and its outputs on the same dataset corrupted with different combinations of the noise level. According to the results of Kendall and Spearman measures, Gini index (GI) and information gain (IG) have the best performances respectively. Nevertheless, both Kendall and Spearman measures results show that ReliefF (RF) is the most sensitive (the worst) performance.

Abstract: In this paper, we propose a model of TopCPathSim in order to
address the problem related to topic-driven similarity searching based on
constrained meta-path (or also called restricted meta-path) between
same-typed objects within the content-based heterogeneous information
networks (HINs). The topic distributions over content-based objects such as:
paper/article on the bibliographic network or users comments/reviews on the
social networks, etc. are obtained by using the LDA topic model. We conduct
the experiments on the real DBLP, Aminer and ACM datasets which
demonstrate the effectiveness of our proposed model. Throughout experiments,
our proposed model gains about 73.56% in accuracy. The output results also
show that the combination of probabilistic topic model with constrained
meta-path is promising to leverage the output quality of topic-oriented
similarity searching in content-based HINs.

by Madhu Priya G, S. Mercy Shalinie, P. Mohana Priya
Abstract: Today's business enterprise adapts cloud based services as its architectural design. Intelligence technique incorporated into the architecture gives massive tangible and intangible benefits in terms of performance and reliability. Such cloud based business architecture faces many threats towards its availability. DDoS attack is the most prominent threat as its impact is more in the virtual resource based cloud infrastructure. Therefore, there is a need for a Business Intelligence based framework to detect early the attack by monitoring the virtual network traffic. The proposed intelligence framework uses a deep learning framework, Continuous Discriminative-Deep Belief Network (CD-DBN). CD-DBN dynamically captures attack patterns from the network data, analyzes the data and detects the intrusion to the cloud. The observed result shows that the earlier detection approach guarantees the availability of cloud services to the legitimate users and enhances the cloud resource usage.

A Simple Transform Domain Based Low Level Primitives Preserving Texture Synthesis
by S. Anuvelavan, M. GANESH, P. Ganesan
Abstract: In this work, a new patch-based texture synthesis scheme with
orthogonal polynomials model coefficients is presented. The proposed scheme
has four phases. In the first phase, a block matching technique that identifies a
best match, to synthesis in the output image of bigger size is designed in terms
of ordered orthogonal polynomials model coefficients. In case of successful
match of block, called patch-hit, the proposed scheme finds candidate blocks
with triangular search, in the next phase. In the patch selection phase, the
proposed scheme considers a subset of orthogonal polynomials model
coefficients among the blocks, for the purpose of synthesis which consumes
less memory and time. This synthesised output is smoothened in the final
phase, by preserving the low level contents between the synthesised patches.
The performance of the proposed scheme is measured with energy, contrast,
correlation, homogeneity and entropy between the original and synthesised
images and is also compared with existing texture synthesis schemes. The
results are encouraging.

by C. Shanmugam, E. Chandira Sekaran
Abstract: Infrared thermography (IRT) has played an essential part in
observing and examining thermal defects of electrical equipment without
ending, which has vital enormity for the dependability of electrical recorded.
This paper dissected the electrical parts are faulted or non-faulted with the help
of segmentation and classification model. The features are calculated from the
input thermal images and regions of interest (ROI) is segmented by utilising
optimal region growing (ORG) technique and faults are classified using multi
kernel support vector machine (MKSVM). In the tests, the classification
performances from different input features are assessed. For enhancing the
performance of the segmentation investigation optimisation procedure that is
whale optimisation (WO) is used. Before classifying, the extracted electrical
components are fused by using feature level fusion (FLF) procedure to fused
vector in all images. These multi Kernel classification performance indices,
including sensitivity, specificity and accuracy are utilised to recognise the most
appropriate input feature and the best arrangement of classifiers. The
performance of SVM is contrasted with a neural network. The correlation
comes about demonstrating that our technique can accomplish a superior
performance with accuracy at 98.21%.

proposed model can generate the meaningful ranking results within detected
topic-driven communities.

algorithm, is used to determine the software effort estimation. AGS is hybrid
method combining three techniques, namely: adaptive neuro fuzzy inference
system (ANFIS), genetic algorithm and satin bower bird optimisation (SBO)
algorithm. The performance of the proposed method is assessed using a well
standard dataset with real-time benchmark with many attributes. The major
metrics used in the performance evaluation are correlation coefficient (CC),
kilo lines of code (KLoC) and complexity of the software. The experimental
result shows that the prediction accuracy of the proposed model is better than
the existing algorithmic models.

Abstract: Feature selection is an important process in text classification. In
general, traditional feature selection approaches are based on exhaustive search
hence become inefficient due to a large search space. Further, this task becomes
more challenging as the number of features increases. Recently, evolutionary
computation (EC)-based search techniques have received a lot of attention in
solving feature selection problem in high-dimensional feature space. This paper
proposes a particle swarm optimisation (PSO)-based feature selection approach
which is capable of generating the desired number of high-quality features from
a large feature space. The proposed algorithm is tested on a large dataset and
compared with several existing state-of-the-art algorithms used for feature
selection. The accuracy of the underlying classifier has been considered as a
measure of performance. Our obtained results demonstrated that the proposed
PSO-based feature selection approach outperforms the other traditional feature
selection algorithms in all the considered classifiers.

Using bagging to enhance clustering procedures for planar shapes
by Elaine Cristina De Assis, Renata Souza, Getulio José Amorim Do Amaral
Abstract: Partitional clustering algorithms find a partition maximizing or minimizing some numerical criterion. Statistical shape analysis is used to make decisions observing the shape of objects. The shape of an object is the remaining information when the effects of location, scale and rotation are removed. This paper introduces clustering algorithms suitable for planar shapes. Four numerical criteria are adapted to each algorithm. In order to escape from local optima to reach a better clustering, these algorithms are performed in the framework of Bagging procedures. Simulation studies are carried to validate these proposed methods and two real-life data sets are also considered. The experiment quality is assessed by the corrected Rand index and the results the application of the proposed algorithms showed the effectiveness of these algorithms using different clustering criteria and the union of the Bagging method to the cluster algorithms provided substantial gains in of the quality of the clusters.

Impact of Clustering on quality of Recommendation in Cluster based Collaborative Filtering: an Empirical Study
by MONIKA SINGH, Monica Mehrotra
Abstract: In memory nearest neighbour computation is a typical approach for
collaborative filtering (CF) due to its high recommendation accuracy. However,
this approach fails on scalability; which is the declined performance of the
same due to the rapid increase in the number of users and items in archetypal
merchandising applications. One of the popular techniques to attenuate
scalability issue is cluster-based collaborative filtering (CBCF), which uses
clustering approach to group most similar users/items from complete dataset. In
this work we present a detailed analysis of the impact of clustering in CF
approach. Specifically, we study how the extent of clustering impacts
collaborative filtering systems in terms of quality of predictions, quality of
recommendations, throughput and coverage. Based on the empirical results
obtained from two datasets, Movielens100K and Jester; we conclude that with
increasing number of clusters the quality of predictions, the quality of
recommendations and the throughput are enhanced but the coverage provided
by clustered subsystems declines.

EFFICIENT TEXT DOCUMENT CLUSTERING WITH NEW SIMILARITY MEASURES
by Lakshmi R, S. Baskar
Abstract: In this paper, two new similarity measures, namely distance of term
frequency-based similarity measure (DTFSM) and presence of common
terms-based similarity measure (PCTSM), are proposed to compute the
similarity between two documents for improving the effectiveness of text
document clustering. The effectiveness of the proposed similarity measures is
evaluated on reuters-21578 and WebKB datasets for clustering the documents
using K-means and K-means++ clustering algorithms. The results obtained by
using the proposed DTFSM and PCTSM are significantly better than other
measures for document clustering in terms of accuracy, entropy, recall and
F-measure. It is evident that the proposed similarity measures not only improve
the effectiveness of the text document clustering, but also reduce the
complexity of similarity measures based on the number of required operations
during text document clustering.

XML web quality analysis by employing MFCM clustering Technique and KNN classification
by M. Gopianand, P. Jaganathan
Abstract: The great accomplishment of web search engine is keyword search which is the most trendy search representation for regular consumers. It is permits that the consumer can create the queries without the knowledge of query language and the database schema. So, it is also considered as a user friendly method. The quality of XML web has to be accurate if the exact queries have to be answered. Here we have proposed a method to access the quality of the XML web by analysing the keyword present in the XML web based on the respective keyword search. In our proposed method we collect number of XML documents and are clustered based on the keyword depending on the type of XML files. Modified fuzzy C means (MFCM) is used for clustering. Once the clustering based on the respective keyword is done, we classify the XML web based on quality of the data by utilising KNN classifier.

by S. VENKATESAN, Manimaran Saravanan, Subramanian Venkatnarayanan, Senior Member IEEE
Abstract: This paper discussed merits of novel modified perturb and observe (P&O) maximum power point tracker (MPPT) algorithm for stand-alone solar PV system using interleaved LUO converter with fuzzy logic controller (FLC). The merits of FLC based system are compared with existing system. Analytical expressions of the proposed converter are derived through signal flow graph. The proposed interleaved LUO converter based PV system with fuzzy controller reduces considerable amount of ripple content and also proposed MPPT algorithm creates less hunting around maximum power point. Simulations at different illumination levels are carried-out using MATLAB/Simulink. It also experimentally verified with a typical 40 W solar PV panel. The result confirms the superiority of the proposed system with fuzzy controller.

SoLoMo Cities: Socio-Spatial City Formation Detection and Evolution Tracking Approach
by Sara Elhishi, Mervat Abu-Elkheir, Ahmed Aboul-Fotouh
Abstract: The tremendous growth of telecommunication devices coupled with
the huge number of social media users has revealed a new kind of development
that turning our cities into information-rich smart platforms. We analyse the
role of LBSN check-ins using social community detection methods to extract
city structured communities, which we call SoLoMo cities, using a modified
version of Louvain algorithm, then we track these communities evolution
patterns through a pairwise consecutive matching process to detect behavioural
events changing citys communities. The findings of the experiments on the
Brightkite dataset can be summarised as follows: online users check-in
activities reveal a set of well-formed physical land spaces of citys
communities, the concentration of online social interactions and the formation
of those cities are positively correlated with a percentage of 89%. Finally, we
were able to track the evolution of the discovered communities through
detecting three community behaviour events: survive, grow and shrink.

AN EFFICIENT FEATURE EXTRACTION FOR BIOMETRIC AUTHENTICATION
by Betty P, Mohanageetha D, Jeena Jacob
Abstract: Biometric authentication has received greater significance due to its high uniqueness and performance. The ability of quick and convenient authentication is required due to its widespread demand. Extraction of feature is the primary and important task for effective authentication. Dissimilar chrominance texture pattern (DiCTP) technique is used in this paper for effective feature extraction. Patterns of two sequences are generated from the inter channel information of the image which extracts the coloured texture information of the input. Unique information is generated from RGB and BRG planes of the image which produces a part of diversified chromatic feature vectors. The local binary pattern (LBP) code is generated and added along with the feature vector, which aids to inculcate the greyscale information of the image. The experimental results are formulated using the CASIA Face Image Database Version 5 (DB1) and Indian Face database (DB2) which give considerable improvements over the existing methodology.

Discovery of Rare Association Rules in the Distribution of Lawsuits in the Federal Justice System of Southern Brazil
by Lucia Gruginskie, Guilherme Vaccaro, Leonardo Chiwiakwosky, Attilla Blesz Jr
Abstract: In the context of data mining, infrequent association rules may be beneficial for analysing rare or extreme cases with very low support values and high confidence. In researching risky situations or allocating specific resources, such rules may have a much greater impact than rules with high support value. The objective of this study is to obtain association rules from the database of lawsuits filed in the Federal Court of Southern Brazil in 2016, including both frequent and rare rules. By finding these rules, especially rare ones, the information collected can assist in the decision-making process, in this case, such as training clerks or establishing specialised courts.

Integral Verification and Validation for Knowledge Discovery Procedure Models
by Anne Antonia Scheidler, Markus Rabe
Abstract: This paper explains why the knowledge discovery in database (KDD) procedure models lacks verification and validation (V&V) mechanisms and introduces an approach for integral V&V. Based on a generic model for knowledge discovery, a structure named 'KDD triangle model' is presented. This model has a modular design and can be adapted for other KDD procedure models. This has the benefit of allowing existing projects for improving their quality assurance in knowledge discovery. In this paper, the different phases of the developed triangle model for KDD are discussed. One special focus is on the phase results and related testing mechanisms. This paper also describes possible V&V techniques for the developed integral V&V mechanism to ensure direct applicability of the model.

A Multiclass Classification Approach for Incremental Entity Resolution on Short Textual Data
by Denilson Pereira, João A. Silva
Abstract: Several web applications maintain data repositories containing references to thousands of real-world entities originating from multiple sources, and they continually receive new data. Identifying the distinct entities and associating the correct references to each one is a problem known as entity resolution. The challenge is to solve the problem incrementally, as the data arrive, especially when those data are described by a single textual attribute. In this paper, we propose a new approach for incremental entity resolution. The method we have implemented, called AssocIER, uses an ensemble of multiclass classifiers with self-training and detection of novel classes. We have evaluated our method in various real-world datasets and scenarios, comparing it with a traditional entity resolution approach. The results show that AssocIER is effective and efficient to solve unstructured data in collections with a large number of entities and features, and is able to detect hundreds of novel classes.

Method for Improvement of Transparency: Use of Text Mining Techniques for Reclassification of Governmental Expenditures Records in Brazil
by Gustavo De Oliveira Almeida, Kate Revoredo, Claudia Cappelli, Cristiano Maciel
Abstract: Many countries have transparency laws requiring availability of data. However, often data is available but not transparent. We present the Transparency Portal of Brazilian Federal Government case and discuss limitations of public acquisitions data stored in free text format. We employed text-mining techniques to reclassify descriptive texts of measurement units related to products and services. The solution presented in KNIME and JAVA aggregated measurements in the original (n = 69,372 with 78% reduction in number of descriptions, 94% items classified) and in cross validation sample (n = 105,266 with 88% reduction, classifying 78% of items). In addition, we tested computational time for processing of texts for a wide range of data input sizes, suggesting the stability and scalability of the solution to process larger datasets. Finally, we produced analysis identifying probable input errors, suppliers and purchasing units with abnormal transactions and factors affecting procurement prices. We present suggestions for future research and improvements.

Data Mining in Credit Insurance Information System for Bank Loans Risk Management in Developing Countries
by Fouad J. Al Azzawi
Abstract: The task of credit risk insurance in our time is critical since loans
are taken by everyone and everywhere and it is quite difficult to accurately
estimate the possible losses that are incurred by failing to pay those loans.
This work proposes an information system module for the banking system to
improve the risk management operation that distributes losses on some fair
basis, as well as accepting the maximum number of loan requests. Insuring the
risk associated with stumbled loans, the bank will partially or completely shift
losses under this contract to the insurance company, thus minimising its own
losses. The proposed module could find out for what price the bank can buy
such insurance policy. The proposed module also could be a key valuable
motivation for different development countries to update their strategy of
current insurance market to outsource part of the states insurance functions to
independent insurance industry. Data mining techniques and mathematical
induction have been used and successfully implemented this model. An optimal
classification solution module for predicting risky loan requests have been
successfully employed. New mathematical model has been developed for
calculating the cost of insurance policy in crisis economy.

by Mohd Fauzi Ramli, AHMAD KADRI JUNOH, Mahyun Ab Wahab, Wan Zuki Azman Wan Muhamad
Abstract: Fibonacci retracement implicates a forecast of future movements in
foreign exchange rates (forex) of the previous movement inductive analysis.
Fibonacci ratios are used to forecast the retracements level of 0.382, 0.500 and
0.618 and to determine the current trend which provide the mathematical
foundation for the Elliott wave theory. K-nearest neighbour (KNN) and linear
discriminant analysis (LDA) algorithm are the pattern recognition method for
nonlinear feature mining of Elliott wave patterns. Results show that LDA is
better than KNN in terms of classification accuracy data which are 99.43%.
Among of three levels of Fibonacci retracement results, the 38.2% shows the
best forecasting for Great Britain Pound pair to US Dollar currency as major
pair by using mean absolute error (MAE), root mean square error (RMSE) and
pearson correlation coefficient (r) as the statistical measurements which are
0.001884, 0.000019 and 0.992253 for uptrend and 0.001685, 0.000019 and
0.998806 for downtrend.

CARs-RP: Lasso Based Class Association Rules Pruning
by AZMI Mohamed, Abdelaziz Berrado
Abstract: Classification based on association rules gets more and more interest in research and practice. In many contexts, rules are often mined from sparse data in high-dimensional spaces, which leads to large number of rules with considerable containment and overlap. Pruning is often used in search for an optimal subset of rules. This paper introduces a method for class association rules (CARs) pruning. It learns weights for a set of CARs by maximising the likelihood function subject to the sum of the absolute values of the weights. The pruning strength is controlled by a shrinkage parameter ?. The suggested method allows the user to choose the appropriate subset of CARs. This is achieved based on a trade-off between the accuracy and complexity of the resulting classifier which is controlled by changing ?. Experimental analysis shows that the introduced method allows to build more concise classifiers with comparable accuracy to other methods.

PPM-HC: a Method for Helping Project Portfolio Management Based on Topic Hierarchy Learning
by Ricardo M. Marcacini, Ricardo A. M. Pinto, Flavia Bernardini
Abstract: The projects categorisation is a crucial step in the project portfolio management (PPM). Categorising projects allows the organisation to identify categories with a lack or excess of projects, according to its strategic objectives. In this work, we present a new method for project portfolio management based on hierarchical clustering (PPM-HC) to organise the projects at several levels of abstraction. In the PPM-HC, similar projects are allocated to the same clusters and subclusters. PPM-HC automatically learns an understandable topic hierarchy from the project portfolio dataset, thereby facilitating the (human) task of exploring, analysing and prioritising the projects of the organisation. We also proposed a card sorting-based technique which allows the evaluation of the projects categorisation using an intuitive visual map. We carried out an experimental evaluation based on a benchmark dataset and we also presented a real-world case study. The results show that the proposed PPM-HC method is promising.

An efficient approach for Defect Detection in Texture analysis using Improved Support Vector Machine
by Manimozhi I., Janakiraman S.
Abstract: Texture defect detection can be defined as the process of determining the location and size of the collection pixels in a textures image which deviate in their intensity values or spatial in compression to a background texture. The detection of abnormalities is a very challenging problem in computer vision. In our proposed method we have designed a method for detecting the defect of pattern texture analysis. Initially, features are extracted from the input image using the gray level co-occurrence matrix (GLCM) and gray level run-length matrix (GLRLM). Then the extracted features are fed to the input of classification stage. Here the classification is done by improved support vector machine (ISVM). The proposed pattern analysis the traditional support vector machine is improved by means of kernel methods. Final stage is the classified features are segmented using the modified fuzzy C means algorithm (MFCM).

A DYNAMIC REPLICATIVE K-MEANS WITH SELF-COMPILING PARTICLE SWARM INTELLIGENCE FOR DATASET CLASSIFICATION
by A. M. Viswa Bharathy
Abstract: The classification techniques proposed so far is not sufficiently intelligent in classifying data set beyond two level classifications. To multi classify the data set for network data we are in need of more hybrid algorithms. In this paper we propose a hybrid technique by combining a modified K-means algorithm called dynamic replicative K-means (DRKM) with self-compiling particle swarm intelligence (SCPSI). The dataset we have chosen for the experiment is KDD Cup 99. The DRKM-SCPSI performs better in terms of detection rate (DR), false positive rate (FPR) and accuracy which is visible from the results presented.

PORTFOLIO SELECTION WITH SUPPORT VECTOR REGRESSION: MULTIPLE KERNELS COMPARISON
by Pedro Alexandre Henrique, Pedro Albuquerque, Peng Yao Hao, Sarah Sabino
Abstract: This study aimed to verify whether the use of support vector regression (SVR) makes the portfolios return exceed the market. For such propose, SVR was applied for 15 different kernel functions to select the best stocks for each quarter, calculating the quarterly portfolio return and cumulative return along the period. Subsequently, the returns of these portfolios were compared with the returns of a market benchmark. Whites (2000) test was applied to avoid the data-snooping effect in assessing the statistical significance of the portfolios developed by the training strategies. The portfolio selected by SVR with inverse multiquadric kernel presented the highest cumulative return of 374.40% and a value at risk (VaR) of 6.87%.The results of this study corroborate the superiority hypothesis of the innovative method of Support Vector Regression in the formation of portfolios, thus constituting a robust predictive method capable to cope with high dimensionality interactions.

Worldwide Gross Revenue Prediction for Bollywood Movies using Hybrid Ensemble Model
by Alina Zaidi, Siddhaling Urolagin
Abstract: Prediction of revenue before a movie is released can be very beneficial for stakeholders and investors in the movie industry. Even though Indian cinema is a booming industry, the literature work in the field of movie revenue prediction is more inclined towards non-Indian movie. In this study we built a novel hybrid prediction model to predict worldwide gross for Bollywood movies. Bollywood movies dataset is prepared by downloading movie related features from IMDb and YouTube movie trailers which consisting of 674 movies. K-means clustering is performed on the movie dataset and two major clusters are identifier. Important features specific to clusters are selected. The proposed hybrid prediction model performs segregation of movies into two clusters and employs prediction model for each cluster. Prediction models we tested included various basic machine learning models and ensemble models. The ensemble model that combined predictions from support vector regression, neural network and ridge regression gave us the best result for both clusters and we chose it to be our final model. We obtain an overall MAE of 0.0272 and R2 of 0.80 after 10-fold cross validation.

Survey on-demand: A versatile scientific article automated inquiry method using text mining applied to Asset Liability Management
by Pedro Henrique Albuquerque, Igor Nascimento, Peng Yao Hao
Abstract: We proposed a methodology that automatically relate content of text documents with lexical items. The model estimates whether an article addresses a specific research object based on the relevant words in its abstract and title using text mining and partial least square discriminant analysis. The model is efficient in accuracy and the adjustment and validation indicators are either superior or equal to the other models in the literature on text classification. In comparison to existing methods, our method offers highly interpretable outcomes and allows flexible measurements of word frequency. The proposed solution may aid scholars regarding the process of searching theoretical references, suggesting scientific articles based on the similarities among the used vocabulary. Applied to the finance area, our framework has indicated that approximately 10% of the publications in the selected journals that address the subject of asset liability management. Moreover, we highlight the journals with the largest number of publications over time and the key words about the subject using only freely accessible information.

The approach of using ontology as pre-knowledge source for semi-supervised labelled topic model by applying text dependency graph
by Phu Pham, Phuc Do
Abstract: Multiple topics discovering from text is an important task in text mining. From the past, the supervised approaches fail to explore multiple topics in text. The topic modelling approach, such as: LSI, pLSI, LDA, etc. are considered as an unsupervised method which supports to discover distributions of multiple topics in text documents. The labelled LDA (LLDA) model is a supervised method which enables to integrate human labelled topics with the given text corpus during the process of modelling topics. However, in real applications, we may not have enough high qualified knowledge to properly assign the topics for all documents before applying the LLDA. In this paper, we present two approaches which are taken the advantage of dependency graph-of-words (GOW) in text analysis. The GOW approach uses frequent sub-graph mining (FSM) technique to extract graph-based concepts from text. Our first approach is method of using graph-based concepts for constructing domain-specific ontology. It is called GC2Onto model. In our second approach, the graph-based concepts are also applied to improve the quality of traditional LLDA. It is called LLDA-GOW model. We combine two GC2Onto and LLDA-GOW models to leverage the multiple topic identification as well as other mining tasks in text.

RFID BI Mobility and Producer to Consumer Traceability Architecture
by Andre Claude Bayomock Linwa
Abstract: Radio frequency identifier (RFID) emerged in 2000 an intelligent remote object identification. RFID helps tracking object position and relevant information using radio frequency technology (Bouet and dos Santos, 2008; Pais, 2010). Its application in industries, highly increases the inventory management consistency and accuracy, by capturing in real-time observed object attributes for traceability and quality control purpose. In order to provide traceability and quality control services, RFID applications should offer two main services: business intelligence (BI) and mobility management. The RFID BI provides production traceability services (QoS metrics related to manufacturing processes). And RFID mobility service maintains accurate RFID tag location. In this paper, a generic RFID BI mobility' data model is defined. In the proposed data model, RFID product information generated by a supply chain organisation is translated or migrated from a producer to a consumer. This migration generates two distinct types of RFID mobility: internal (inside buildings) and external.

Sentimental Event Detection from Arabic Tweets
by Mohammad Daoud, Daoud Daoud
Abstract: This article presents and evaluates an approach to detect sentimental events from Twitter Arabic data streams. Sentimental events attract strongly opinionated responses from the online community; therefore, we aim at detecting the association of a topic with a positive or a negative sentiment at a particular time. To achieve that, we build sentimental time series where the frequencies of that association (between topics and sentiment) are recorded. And then, we use several algorithms to locate possible events. Events in positive timelines will be considered as positive, and similarly for negative events. Our approaches use Shannon diversity index and hill climbing peak finding. We experimented our proposed algorithms with the domain of football (soccer) news. The results showed good precision and recall considering mainstream media as a reference. The success of such experiment can open the door for many useful applications including reputation and brand monitoring systems for various domains and languages.

A comparison of cluster algorithms as applied to unsupervised surveys
by Kathleen C. Garwood, Arpit Dhobale
Abstract: When considering answering important questions with data, unsupervised data offers extensive insight opportunity and unique challenges. This study considers student survey data with a specific goal of clustering students into like groups with underlying concept of identifying different poverty levels. Fuzzy logic is considered during the data cleaning and organising phase helping to create a logical dependent variable for analysis comparison. Using multiple data reduction techniques, the survey was reduced and cleaned. Finally, multiple clustering techniques (k-means, k-modes and hierarchical clustering) are applied and compared. Though each method has strengths, the goal was to identify which was most viable when applied to survey data and specifically when trying to identify the most impoverished students.

Discovery of inconsistent generalized coherent rules
by Anuradha Radhakrishnan, Rajkumar N, Rathi Gopalakrishnan, Soosaimichael PrinceSahayaBrighty
Abstract: Mining multiple-level association rules in a predefined taxonomy is an hierarchies that paves the way for generalised rule mining using interestingness measures like support and confidence. Coherent rule mining identifies significant rules in a database without using interestingness measures. In this paper we propose a new mining algorithm called generalised inconsistent coherent rule mining (GICRM) for mining a new form of generalised coherent rules called Inconsistent coherent rules. The discovered rules are called inconsistent because the correlation of the rules changes from one level of taxonomy to another. The rules are mined from a structured dataset of predefined taxonomy. The inconsistent rules mined would be noteworthy at business point of view for taking strategic decisions in market basket analysis.
Keywords: GICRM; multiple-level; generalized inconsistent coherent rule; taxonomy.

Time and Structural Anomalies Detection in Business Processes Using Process Mining
by Elham Saeedi, Faramarz Safi-Esfahani
Abstract: Information systems are increasingly being integrated into operational process and as a result, many events are recorded by information systems. Lack of compatibility between the process model and the observed behaviour is one of the challenges in constructing the process model in process mining. This lack of compatibility could be present in both the structure (sequence of the task) and the time spent in each task. In this paper, a hybrid approach for detecting structural and time anomalies via process mining is proposed. A dataset form Iran Insurance Company is used for performing a case study. The proposed method has detected 98.5% of structure anomalies and 96.3% of time anomalies which is one of the main achievements of this paper. A second standard dataset is used to further examine the proposed method that referred to as dataset 2. The proposed method has demonstrated a better performance compared with the baseline approach.
Keywords: Process mining; conformance checking; workflow mining; structural anomaly; time anomaly; flexible model; Insurance anomaly; anomaly detection; process model; control-flow perspective.

The integration of a newly defined N-gram concept and vector space model for documents ranking
by Mostafa A. Salama, Wafaa Salah
Abstract: Vector space model (VSM) is used in measuring the similarity between documents according to the frequency of common words among them. Furthermore, the N-gram concept is integrated in VSM to put into consideration the relation between common consecutive words in the documents. This approach does not consider the context and semantic dependency between nonconsecutive words existing in the same sentence. Accordingly, the approach proposed here presents a new definition of the N-gram concept as N non-consecutive words located in the same sentence, and utilises this definition in the VSM to enhance the measurement of the semantic similarity between documents. This approach measures and visualises the correlation between the words that are commonly existing together within the same sentence to enrich the analysis of domain experts. The results of the experimental work show the robustness of the proposed approach against the current ranking models.
Keywords: N-gram; vector space model; VSM; text mining.

Master node fault tolerance in distributed big data processing clusters
by Ivan Gankevich, Yuri Tipikin, Vladimir Korkhov, Vladimir Gaiduchok, Alexander Degtyarev, A. Bogdanov
Abstract: Distributed computing clusters are often built with commodity hardware which leads to periodic failures of processing nodes due to relatively low reliability of such hardware. While worker node fault-tolerance is straightforward, fault tolerance of master node poses a bigger challenge. In this paper master node failure handling is based on the concept of master and worker roles that can be dynamically re-assigned to cluster nodes along with maintaining a backup of the master node state on one of worker nodes. In such case no special component is needed to monitor the health of the cluster while master node failures can be resolved except for the cases of simultaneous failure of master and backup. We present experimental evaluation of the technique implementation, show benchmarks demonstrating that a failure of a master does not affect running job, and a failure of backup results in re-computation of only the last job step.
Keywords: parallel computing; big data processing; distributed computing; backup node; state transfer; delegation; cluster computing; fault-tolerance; high-availability; hierarchy.

Students performance prediction using hybrid classifier technique in incremental learning
by Roshani Ade
Abstract: The performance in higher education is a turning point in the academics for all students. This academic performance is influenced by many factors, therefore, it is essential to develop predictive data mining model for student's performance so as to identify the difference between high learners and slow learners student. The knowledge is hidden among the educational data set and it is extractable through data mining techniques. In our paper, we used the hybrid classifier approach for the prediction of student's performance using fuzzy ARTMAP and Bayesian ARTMAP classifier. Sensitivity analysis was performed and irrelevant inputs were eliminated. The performance measures used to determine the performance of the techniques include Matthews correlation coefficient (MCC), accuracy rate, true positive, false positive and percentage correctly classified instances. The combined result gives the good accuracy for predicting students' performance while using this approach. Thus, an enhanced prediction method for students is obtained.

Combined local colour curvelet and mesh pattern for image retrieval system
by Yesubai Rubavathi Charles
Abstract: This manuscript presents the content based image retrieval system using new textural features such as colour local curvelet (CLC) based textural descriptor and colour local mesh pattern (CLMP), for the intention of increasing the performance of the image retrieval system. The proposed methods can be able to utilise the distinctive details obtained from spatial coloured textural patterns of various spectral components within the particular local image region. Furthermore, to acquire the benefit of harmonising effect through joint colour texture information, the oppugant colour textural features that obtain the texture patterns of spatial interactions among spectral planes are also integrated in to the creation of CLC and CLMP. Extensive and comparative experiments have been conducted on two benchmark databases, i.e., Corel-1k, MIT VisTex. Retrieval results show that image retrieval using colour local texture features yields better precision and recall than retrieval approaches using either by colour or texture features.
Keywords: content-based image retrieval system; curvelet transform; local mesh pattern; local colour curvelets; LCC; local colour mesh pattern; LCMP.

Fuzzy-based automated interruption testing model for mobile applications
by A. Malini, K. Sundarakantham, C. Mano Prathibhan, A. Bhavithrachelvi
Abstract: Testing of mobile applications during the occurrence of interrupts is termed as interrupt testing. Interrupts can occur either internally within the mobile or from other external factors or systems. Interruption in any smart phones may decrease the performance of mobile applications. In this paper, an automated interruption testing model is proposed to analyse the responsiveness of mobile applications during interrupts. This model monitors the applications installed in the mobile devices and evaluates the overall performance of mobile applications during interrupt using fuzzy logic. An enhanced MobiFuzzy evaluation system (MFES) is proposed that is used to dynamically analyse the test results and identify necessary information required for tuning the application. Fuzzy logic will help the developers or testers in tuning the application performance; by automatically categorising the impact level of performance parameters on the overall performance of the application.

by M. Senthil Kumar, P.S. Manoharan, R. Ramachandran
Abstract: This paper presents modelling and simulation of artificial neuro-fuzzy inference system (ANFIS)-based maximum power point tracking (MPPT) algorithm for PV system with modified SEPIC converter. The conventional existing MPPT methods are having major drawbacks of high oscillations at maximum power point and low efficiency due to uncertain nature of solar radiation and temperature. These mentioned problems can be solved by the proposed adaptive (ANFIS)-based MPPT. The proposed work involves ANFIS and modified single ended primary inductor converter (SEPIC) to extract maximum power from PV panel. The results obtained from proposed methodology are compared with other MPPT algorithms such as perturb and observe (P&O), incremental conductance (INC) and radial basis function network (RBFN). The improvement in voltage rating of modified SEPIC is compared with conventional SEPIC converter. The result confirms the superiority of the proposed system.

by Balasaheb Tarle, Sudarson Jena
Abstract: The ultimate aim of the proposed method is to establish a model for classification of medical data. Various methods have been generated to health related data to detect upcoming health fitness usage including detecting person's spending and illness related issues for diseased persons. In order to achieve promising results in medical data classification, we have planned to utilise orthogonal local preserving projection and optimal classifier. Initially, the pre-processing will be applied for extracting useful information and to convert suitable sample from raw medical datasets. Here, orthogonal local preserving projection (OLPP) is used to reduce the feature dimension. Once the feature reduction is formed, the prediction will be done based on the optimal classifier. In the optimal classifier, artificial bee colony algorithm will be used with neural network. The effectiveness of our proposed is measured in terms of accuracy, sensitivity and specificity. Here, Switzerland dataset achieves the maximum accuracy value 95.935%.

by T. Keerthika, K. Premalatha
Abstract: In today's modern world cardiovascular disease is the most lethal one. This disease attacks a person so instantly that it hardly gets any time to get treated with. So, diagnosing patients correctly on timely basis is the most challenging task for the medical fraternity. In order to reduce the risk of heart disease, effective feature selection and classification based prediction system is proposed. An efficient feature selection is applied on the high dimensional medical data, for selecting the features fish swarm optimisation algorithm is used. After that, selected features from medical dataset are fed to the HKSVM for classification. The performance of the proposed technique is evaluated by accuracy, sensitivity, specificity, precision, recall and f-measure. Experimental results indicate that the proposed classification framework have outperformed by having better accuracy of 96.03% for Cleveland dataset when compared existing SVM method only achieved 91.41% and optimal rough fuzzy classifier achieved 62.25%.
Keywords: hybrid kernel support vector machine; HKSVM; feature selection; fish swarm optimisation; support vector machines; SVM; optimal rough fuzzy; Cleveland; Hungarian; Switzerland.
The complexity of cluster-connectivity of wireless sensor networks
by H.K. Dai, H.C. Su
Abstract: Wireless sensor networks consist of sensor devices with limited computational capabilities and memory operating in bounded energy resources; hence, network optimisation and algorithmic development in minimising the total energy or power while maintaining the connectivity of the underlying network are crucial for their design and maintenance. We consider a generalised system model of wireless sensor networks whose node set is decomposed into multiple clusters, and show that the decision and the associated minimisation problems of the connectivity of clustered wireless sensor networks appear to be computationally intractable - completeness and hardness, respectively, for the non-deterministic polynomial-time complexity class. An approximation algorithm is devised to minimise the number of end nodes of inter-cluster edges within a factor of 2 of the optimum for the cluster-connectivity.
Keywords: wireless sensor network; connectivity; spanning tree; non-deterministic polynomial-time complexity class; approximation algorithm.

A fast clustering approach for large multidimensional data
by Hajar Rehioui, Abdellah Idrissi
Abstract: Density-based clustering is a strong family of clustering methods. The strength of this family is its ability to classify data of arbitrary shapes and to omit the noise. Among them density-based clustering (DENCLUE), which is one of the well-known powerful density-based clustering methods. DENCLUE is based on the concept of the hill climbing algorithm. In order to find the clusters, DENCLUE has to reach a set of points called density attractors. Despite the advantages of DENCLUE, it remains sensitive to the growth of the size of data and of the dimensionality, in the fact that the density attractors are calculated of each point in the input data. In this paper, in the aim to overcome the DENCLUE shortcoming, we propose an efficient approach. This approach replaces the concept of the density attractor by a new concept which is 'the hyper-cube representative'. The experimental results, provided from several datasets, prove that our approach finds a trade-off between the performance of clustering and the fast response time. In this way, the proposed clustering methods work efficiently for large of multidimensional data.
Keywords: large data; dimensional data; clustering; density-based clustering; DENCLUE.
