• 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.

• 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.

• Mining Big data streams using Business analytics tools: A bird  
  by Arunkumar PM, S. Kannimuthu 
  Abstract: Big data evolves as the prominent field in modern computing era. Big data analytics and its impact on extracting business intelligence is becoming indispensable for plethora of applications. 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.

• 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.

• 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.

  Abstract: Opinion Mining is an ongoing research area in E-commerce which aims at analyzing the people's opinions, sentiments and emotions. Moreover, the existing E-commerce systems allow the users to share their feedback in the form of textual reviews regarding the products and services. It also allows the consumers to give ratings for products that help in future recommendation of products. In this research work, a computational framework for efficiently predicting the consumer review ratings on the products has been proposed. The proposed framework integrates Dimensionality Reduction, Genetic Algorithm, Fuzzy C-Means and Adaptive Neuro-Fuzzy Inference techniques to overcome the limitations of the existing systems. Experiments have been conducted in this work using Amazon dataset consisting of reviews for different products. This system provides better performance and prediction accuracy for review ratings when it is compared with the related work.

  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.

  by Bolanle Ojokoh, Oluwatosin Olatunbosun Aboluje, Tobore Igbe 
  Abstract: In this paper, Pearson's correlation coefficient is employed for collaborative filtering due to its ability to manipulate numerical data as well as determine linear relationship among existing users. Its steps involve a user-user representation, similarity generation and prediction generation with a goal to produce a predicted opinion of the active user about a specific item. Concept of parental control is also incorporated for enhancement. Evaluation of the system was done using precision, recall, F-measure, discounted cumulative gain (DCG), idealised discounted cumulative gain (IDCG), normalised discounted cumulative gain (nDCG) and mean absolute error (MAE). Three hundred fortysix datasets were used, out of which 126 were gathered from local video shops and 220 were extracted from internet movie database (IMDb). These were used for the experiments and the results generated through mining of data obtained from profiles and ratings of system users prove the system's average ranking quality of the collaborative filtering algorithm is 95.9%.

• 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.

• Topic-driven top-k similarity search by applying constrained meta-path based in content-based schema-enriched heterogeneous information network  
  by Phu Pham, Phuc Do 
  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.

• Deep learning framework for early detection of intrusion in Virtual Environment  
  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.

• Optimal Region growing and Multi-kernel SVM for fault detection in Electrical Equipments using Infrared Thermography Images  
  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%.

  by Phu Pham, Phuc Do 
  Abstract: In this paper, we propose the ComRank model to address this problem of ranking a specific typed of object, over the generated topic-driven communities in the information networks. The topic-driven communities are generated by applying the latent topic modelling of LDA. Our proposed ComRank model is directly generated ranking results for specific typed object in the different network communities. We apply our approach to construct the scholastic recommendation system, which support the researchers to find the appropriate citations or potential authors for cooperating while doing scientific researches. The ComRank model is tested with the real-world dataset of DBLP bibliographic network. The experimental results demonstrated that our proposed model can generate the meaningful ranking results within detected topic-driven communities.

  Abstract: To predict the amount of effort to develop software is a tedious process for software companies. Hence, predicting the software development effort remains a complex issue drawing in extensive research consideration. The success of software development process considerably depends on proper estimation of effort required to develop that software. Effective software effort estimation techniques enable project managers to schedule software life cycle activities properly. The main objective of this paper is to propose a novel approach in which an artificial intelligence (AI)-based technique, called AGS 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.

• High dimensional sentiment classification of product reviews using evolutionary computation  
  by Sonu Lal Gupta, Anurag Singh Baghel 
  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.

• Fibonacci Retracement Pattern Recognition for Forecasting Foreign Exchange Market  
  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.

  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.
  Keywords: Fuzzy logic; cluster analysis; unsupervised learning; survey analysis; decision support system; k-means; k-modes; hierarchical clustering.

• 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.

• Stock Price Forecasting and News Sentiment Analysis Model using Artificial Neural Network  
  by Sriram K. V, Somesh Yadav, Ritesh Singh Suhag 
  Abstract: The stock market is highly volatile, and the prediction of stock prices has always been an area of interest to many statisticians and researchers. This study is an attempt to predict the prices of stock using Artificial Neural Network (ANN). Three models have been built, one for the future prediction of stock prices based on previous trends, the second for prediction of next day closing price based on today’s opening price, and the third one analyzes the sentiment of news articles and gives scores based on the news impact. ANN is trained with the historical data using R-studio platform which is then used to predict the future values. Our experimental results for various stock prices showed that the model is effective using ANN.

  by Everton Castelão Tetila, Bruno Brandoli Machado, Jose F. Rorigues-Jr, Nícolas Alessando De Souza Belete, Diego A. Zanoni, Thayliny Zardo, Michel Constantino, Hemerson Pistori 
  Abstract: This paper proposes an associative classification model based on three technical indicators to forecast future trends of stock market. Our methodology assessed the performance of nine technical indicators, using a portfolio of ten stocks and a twelve-year time series. The experimental results showed that the use of a set of technical indicators leads to higher classification rates compared to the use of sole technical indicators, reaching an accuracy of 88.77%. The proposed approach also uses a multidimensional data cube that allows automatic updating of stock market asset values, which are essential to keep the forecast updated. The results indicate that our approach can support investors and analysts to operate in stock market.

• An automated ontology learning for benchmarking classifier models through gain-based relative-non-redundant feature selection: a case-study with erythemato-squamous disease  
  by Sivasankari Sivasubramanian, 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.

• Grey wolf optimiser-based feature selection for feature-level multi-focus image fusion  
  by K. Sujatha, 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.

  by N.R. Ram Mohan, S. Padmalal, B. Chitra 
  Abstract: This paper proposes a green cloud multi-tenant trust authentication with secure hash algorithm-3 (GreenCloud-MTASHA3) scheme to eliminate the unauthorised tenant access. GreenCloud-MTASHA3 scheme provide security over the multiple tenant requests by referring the confidentiality, integrity and availability rate. Confidentiality refers to limiting the unauthorised tenant's green cloud data access using the additive homomorphic privacy property in proposed scheme. Additive homomorphic privacy property-based encryption function is developed to improve the privacy preserving level. To attain the integrity level between the tenant requests and green cloud server machine in GreenCloud-MTASHA3 scheme an encrypted trust data management process is carried out. Trustworthiness of tenant request is measured to maintain the consistency level on security with minimal computational time. The proposed scheme attains the confidentiality, integrity and availability rate on communicating task. Experiment is conducted on factors such as secure computation confidence, authorised tenant computational time and space taken on storing encrypted data.

• 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 dataset 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 correlate 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.

• Unsupervised key frame selection using information theory and colour 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.

  by E.K. Vellingiriraj, P. Balasubrmanie 
  Abstract: The ancient Tamil characters recognition is the complex task because there is no sufficient training information is available. Various researchers attempted to perform accurate recognition of ancient Tamil characters. In our preceding work, hybrid multi-neural learning based prediction and recognition system (HMNL-PRS) is introduced for the prediction process which lacks from inaccurate recognition. In this proposed research work, this is overcome by proposing the Brahmi character prediction and conversion system (BC-PCS) methodology. Here, the modified graph based segmentation algorithm (MGSA) is used to segment the characters. And then the statistical and structural features are extracted based on which classification is done using hybridised support vector machine based fuzzy neural network. In the MATLAB simulation environment, the proposed research work is implemented and it is confirmed that the proposed research work direct to give the excellent result compared to the preceding research methodology in terms of recognition rate.

• A 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.
