by Elena N. Stankova, Andrey V. Balakshiy, Dmitry A. Petrov, Vladimir V. Korkhov
Abstract: In the present work we use the technologies of machine learning and OLAP for more accurate forecasting of such phenomena as a thunderstorm, hail, heavy rain, using the numerical model of convective cloud. Three methods of machine learning: Support Vector Machine, Logistic Regression and Ridge Regression are used for making the decision on whether or not a dangerous convective phenomenon occurs at present atmospheric conditions. The OLAP technology is used for development of the concept of multidimensional data base intended for distinguishing the types of the phenomena (thunderstorm, heavy rainfall and light rain). Previously developed complex information system is used for collecting the data about the state of the atmosphere and about the place and at the time when dangerous convective phenomena are recorded.

Rough Set Theory-Based Feature Selection and FGA-NN Classifier for Medical Data Classification
by B. Vijayalakshmi, Sugumar Rajendran
Abstract: The prediction of heart disease is difficult task, which needs much
experience and knowledge. In order to reduce the risk of heart disease
prediction, in this paper we proposed a rough set theory-based feature selection
and FGA-NN classifier. The overall process of the proposed system consists of
two main steps, such as: 1) feature reduction; 2) heart disease prediction. At
first, the kernel fuzzy c-means clustering with roughest theory (KFCMRS)
algorithm is applied to the high dimensional data to reduce the dimension of the
attribute. After that, the medical data classification is done through FGA-NN
classifier. To improve the prediction performance, hybridisation of firefly and
genetic algorithm (FGA) is utilised with NN for weight optimisation. At last,
the experimentation is performed by means of Cleveland, Hungarian, and
Switzerland datasets. The experimentation result proves that the FGA-NN
classifier outperformed the existing approach by attaining the accuracy of 83%.

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 students 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 Co-efficient (MCC), Accuracy Rate, True Positive, False Positive and Percentage correctly classified instances. The combined result gives the good accuracy for predicting students

Privacy Preserving Data Mining using Hiding Maximum Utility Item First Algorithm By means of Grey wolf optimisation Algorithm
by M.T. Ketthari, Rajendran Sugumar
Abstract: In the privacy preserving data mining, the utility mining casts a very
vital part. The objective of the suggested technique is performed by concealing
the high sensitive item sets with the help of the hiding maximum utility item
first (HMUIF) algorithm, which effectively evaluates the sensitive item sets by
effectively exploiting the user defined utility threshold value. It successfully
attempts to estimate the sensitive item sets by utilising optimal threshold value,
by means of the grey wolf optimisation (GWO) algorithm. The optimised
threshold value is then checked for its performance analysis by employing
several constraints like the HF, MC and DIS. The novel technique is performed
and the optimal threshold resultant item sets are assessed and contrasted with
those of diverse optimisation approaches. The novel HMUIF considerably cuts
down the calculation complication, thereby paving the way for the
enhancement in hiding performance of the item sets.

Fuzzy- MCS algorithm based Ontology generation for E Assessment
by A. Santhanavijayan, S.R. Balasundaram
Abstract: Ontologies can lead to important improvements in the definition of a
courses knowledge domain, in the generation of an adapted learning path, and
in the assessment phase. This paper provides an initial discussion of the role of
ontologies in the context of e-learning. Generally, automatic assessment is
preferred over manual assessment to avoid bias errors, human errors and also
conserves teachers time. Evaluation through objective tests like multiple
choice questions has gained a lot of importance in the e-assessment system.
Here we have proposed an efficient ontology generation based on soft
computing techniques in e-assessment for multiple choice questions. We have
employed fuzzy logic incorporated with optimisation algorithm like modified
cuckoo search algorithm. Here a set of rules are first designed for creating the
ontology. The rules are generated using fuzzy logic and these rules are
optimised in order to generate a better ontology structure.

by N. Chidambararaj, K. Chitra
Abstract: In the paper, a minimal constraint based cuckoo search (CS)
algorithm is proposed for solving transmission congestion problem by
considering both increase and decrease in generation power. Thus, the proposed
algorithm is used to optimise the real power changes of generator while
transmission congestion occurred. Then, the power loss, generator sensitivity
factor and congestion management cost of the system is evaluated by the
proposed algorithm according to the transmission congestion. The proposed
method is implemented in MATLAB working platform and their congestion
management performance is analysed. The performance of the proposed
method is compared with the other existing methods such as fuzzy adaptive
bacterial foraging (FABF), simple bacterial foraging (SBF), particle swarm
optimisation (PSO), and artificial neural network (ANN)-CS respectively. The
congestion management cost is reduced up to 26.169%. Through the analysis of
comparison, it is shown that the proposed technique is better and outperforms
other existing techniques in terms of congestion management measures.

by Nivash J P, L.D. Dhinesh Babu
Abstract: Effective dissemination of knowledge published by eminent authors
in reputed journals and ensuring that the referred work is cited properly is the
need of the hour. Citation analysis is about the similarity measures of articles or
journals which are put forward to scaling as well as clustering procedures. A
proper citation relevancy check (CRC) is required to avoid the missing links in
the citation networks. Both similar and dissimilar references in the articles have
important article citations. The purpose of this work is devise a method to find
the most significant articles which can provide useful information to the journal
editors and writers. The strategy presented in this paper can assist an author to
incorporate most important articles and can help the editor in evaluating the
quality of the references. The main benefit in detecting the missing articles is
improvement in quality of research along with increased citation count.

A Distributed Cross-layer Recommender System Incorporating Product Diffusion
by Ephina Thendral, C. Valliyammai
Abstract: In this era of online retailing, personalisation of web content has
become very essential. Recommender system is a tool for extraction of relevant
information to render personalisation in web information retrieval systems.
With an inclination towards customer oriented service, there is a need to
understand the adaptability of customers, to provide products/services of
interest at the right time. In this paper, a model for distributed context aware
cross layer recommender system incorporating the principle of product
diffusion is proposed. The offline-online modelled recommender system learns
offline about the adaptation time of users using the principle of product
diffusion and then, uses online explore-then-exploit strategy to make effective
recommendations to the user at the most probable time of consumption. Also,
an algorithm based on product adaptability is proposed for recommending new
items to the most probable users. The extensive experiments and results
demonstrate the efficiency, scalability, reliability and enhanced retrieval
effectiveness of the proposed recommender system model.

A Critique of Imbalanced Data Learning Approaches for Big Data Analytics
by Amril Nazir
Abstract: Biomedical research becomes reliant on multi-disciplinary,
multi-institutional collaboration, and data sharing is becoming increasingly
important for researchers to reuse experiments, pool expertise and validate
approaches. However, there are many hurdles for data sharing, including the
unwillingness to share, lack of flexible data model for providing context
information for shared data, difficulty to share syntactically and semantically
consistent data across distributed institutions, and expensive cost to provide
tools to share the data. In our work, we develop a web-based collaborative
biomedical data sharing platform SciPort to support biomedical data sharing
across distributed organisations. SciPort provides a generic metadata model for
researchers to flflexibly customise and organise the data. To enable convenient
data sharing, SciPort provides a central server-based data sharing architecture,
where data can be shared by one click through publishing metadata to the
central server. To enable consistent data sharing, SciPort provides collaborative
distributed schema management across distributed sites. To enable semantic
consistency for data sharing, SciPort provides semantic tagging through
controlled vocabularies. SciPort is lightweight and can be easily deployed for
building data sharing communities for biomedical research.

An optimised approach to detect the identity of
hidden information in gray scale and colour images
by Murugeswari Ganesan, Deisy Chelliah, Ganesan Govindan
Abstract: Feature-based steganalysis is an emerging trend in the domain of
Information Forensics, aims to discover the identity of secret information
present in the covert communication by analysing the statistical features of
cover/stego image. Due to massive volumes of auditing data as well as complex
and dynamic behaviours of steganogram features, optimising those features is
an important open problem. This paper focused on optimising the number of
features using the proposed quick artificial bee colony (qABC) algorithm. Here
we tested for three steganalysers, namely subtractive pixel adjacency matrix
(SPAM), phase aware projection model (PHARM) and colour filter array
(CFA) for the break our steganographic system (BOSS) 1.01 datasets. The
significant improvement in the convergence nature of qABC quickly improves
the solution and fine tune the search than their real counterparts. The results
reveal that qABC method with support vector machine (SVM) classifier
outperforms the non-optimised version concerning classification accuracy and
reduced number of feature sets.

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.

Error Tolerant Global Search Incorporated With Deep Learning Algorithm to Automatic Hindi Text Summarization
by J. Anitha, P.V.G.D. Prasad Reddy, M.S. Prasad Babu
Abstract: There is an exponential growth in the available electronic
information in the last two decades. It causes a huge necessity to quickly
understand high volume text data. This paper describes an efficient algorithm
and it works by assigning scores to sentences in the document which is to be
summarised. It also focuses on document extracts; a particular kind of
computed document summary. The proposed approach uses fuzzy classifier and
deep learning algorithm. Fuzzy classifier produces score for each sentence and
the deep learning (DL) also produces score for each sentence. The combination
of score from both fuzzy classifier and DL produces the hybrid score. Finally,
the summarised text can be generated based on this hybrid score. In our
proposed approach, we have achieved an average precision rate of 0.92 and
average recall rate of 0.88 and the compression rate is 10% according to the

Network Affinity Aware Energy Efficient Virtual Machine Placement Algorithm
by Ranjana Ramamurthy, S. Radha, J. Raja
Abstract: Efficient mapping of virtual machine request to the available
physical machine is an optimisation problem in data centres. It is solved by
aiming to minimise the number of physical machines and utilising them to their
maximum capacity. Another avenue of optimisation in data centre is the energy
consumption. Energy consumption can be reduced by using fewer physical
machines for a given set of VM requests. An attempt is made in this work to
propose an energy efficient VM placement algorithm that is also network
affinity aware. Considering the network affinity between VMs during the
placement will reduce the communication cost and the network overhead. The
proposed algorithm is evaluated using the Cloudsim toolkit and the
performance in terms of energy consumed, communication cost and number of
active PMs, is compared with the standard first fit greedy algorithm.

A Secured Best Data Center Selection in Cloud Computing Using Encryption Technique
by Prabhu A., M. Usha
Abstract: In this work, we have proposed an approach for providing very high security to the cloud system. Our proposed method comprises of three phases namely authentication phase, cloud data centre selection phase and user related service agreement phase. For the purpose of accessing data from the cloud server, we will need a secure authentication key. In the authentication phase, the user authentication is verified and gets the key then encrypts the file using blowfish algorithm. Before encryption the input data is divided into column-wisely with the help of pattern matching approach. In the approach, the encryption and decryption processes are carried out by employing the blowfish algorithm. We can optimally select the cloud data centre to store the data; here the position is optimally selected with the help of bat algorithm. In the final phase, the user service agreement is verified. The implementation will be done by cloud sim simulator.

Combined Local color curvelet and mesh pattern for image retrieval system
by YESUBAI RUBAVATHI
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.

FUZZY BASED AUTOMATED INTERRUPTION TESTING MODEL FOR MOBILE APPLICATIONS
by Malini A, 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

Evolution of Singular Value Decomposition in Recommendation Systems : A Review
by Rachana Mehta, Keyur Rana
Abstract: Proliferation of internet and web applications has led to
exponential growth of users and information over web. In such information
overload scenarios, recommender systems have shown their prominence by
providing user with information of their interest. Recommender systems
provide item recommendation or generate predictions. Amongst the various
recommendation approaches, collaborative filtering techniques have emerged
well because of its wide item applicability. Model-based collaborative
filtering techniques which use parameterised model for prediction are more
preferred as compared to their memory-based counterparts. However, the
existing techniques deals with static data and are less accurate over sparse,
high dimensional data. In order to alleviate such issues, matrix factorisation
techniques like singular value decomposition are preferred. These techniques
have evolved from using simple user-item rating information to auxiliary
social and temporal information. In this paper, we provide a comprehensive
review of such matrix factorisation techniques and their applicability to
different input data.

Investigating Different Fitness Criteria for Swarm-based Clustering
by Maria P.S. Souza, Telmo M. Silva Filho, Getulio J.A. Amaral, Renata M.C.R. Souza
Abstract: Swarm-based optimisation methods have been previously used for
tackling clustering tasks, with good results. However, the results obtained by
this kind of algorithm are highly dependent on the chosen fitness criterion.
In this work, we investigate the influence of four different fitness criteria
on swarm-based clustering performance. The first function is the typical
sum of distances between instances and their cluster centroids, which is the
most used clustering criterion. The remaining functions are based on three
different types of data dispersion: total dispersion, within-group dispersion
and between-groups dispersion. We use a swarm-based algorithm to optimise these criteria and perform clustering tasks with nine real and artificial
datasets. For each dataset, we select the best criterion in terms of adjusted
Rand index and compare it with three state-of-the-art swarm-based clustering
algorithms, trained with their proposed criteria. Numerical results confirm the
importance of selecting an appropriate fitness criterion for each clustering

A Combined PFCM and Recurrent Neural Network based Intrusion Detection System for Cloud Environment
by Manickam M., N. Ramaraj, C. Chellappan
Abstract: The main objective of this paper is intrusion detection system for a
cloud environment using combined PFCM-RNN. Traditional IDSs are not
suitable for cloud environment as network-based IDSs (NIDS) cannot detect
encrypted node communication, also host-based IDSs (HIDS) are not able to
find the hidden attack trail. The traditional intrusion detection is largely
inefficient to be deployed in cloud computing environments due to their
openness and specific essence. Accordingly, this proposed work consists of two
modules namely clustering module and classification module. In clustering
module, the input dataset is grouped into clusters with the use of possibilistic
fuzzy C-means clustering (PFCM). In classification module, the centroid from
the clusters is given to the recurrent neural network which is used to classify
whether the data is intruded or not. For experimental evaluation, we use the
benchmark database and the results clearly demonstrate the proposed technique
outperformed conventional methods.

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.

The integration of a newly defined N-gram concept and vector space model for documents ranking
by Mostafa 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.

MODELLING AND SIMULATION OF ANFISBASED MPPT FOR PV SYSTEM WITH MODIFIED SEPIC CONVERTER
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.

Distributed Algorithms for Improved Associative Multilabel Document Classification considering Reoccurrence of Features and handling Minority Classes
by Preeti Bailke, S.T. Patil
Abstract: Existing work in the domain of distributed data mining mainly
focuses on achieving the speedup and scaleup properties rather than improving
performance measures of the classifier. Improvement in speedup and scaleup is
obvious when distributed computing platform is used. But its computing power
should also be used for improving performance measures of the classifier. This
paper focuses on the same by considering reoccurrence of features and
handling minority classes. Since it is very time consuming to run such complex
algorithms on large datasets sequentially, distributed versions of the algorithms
are designed and tested on the Hadoop cluster. Base associative classifier is
designed based on multi-class, multi-label associative classification (MMAC)
algorithm. Since no similar distributed algorithms exist, proposed algorithms
are compared with the base classifier and have shown improvement in classifier

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.

Abstract: Learning analytics and educational data mining has greatly
supported the process of assessing and improving the quality of education.
While learning analytics has a longer development cycle, educational data
mining suffers from the inadequacy of data captured through learning
processes. The data captured from examination process can be suitably
extended to perform some descriptive and predictive analytics. This paper
demonstrates the possibility of actionable analytics on the data collected from
talent search examination process by adding to it some data pre-processing
steps. The analytics provides some insight into the learners characteristics
and demonstrates how analytics on examination data can be a major support
for bringing the quality in education field.

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.

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.

Enhancing Purchase Decision using Multi-word Target Bootstrapping with Part-of-Speech Pattern Recognition Algorithm
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.

known as membership grades. Rough set theory is potential in categorising data
into equivalent classes and fuzzy logic may be applied through soft thresholds
for refining equivalence relation that quantifies correlation between each class
of elucidated data. In this paper, probabilistic variable precision fuzzy rough set
technique (PVPFRST) is proposed for deriving robust approximations and
generalisations that handles the types of uncertainty namely stochastic,
imprecision and noise in membership functions. The result infers that the
degree of accuracy of PVPFRST is 21% superior to benchmark techniques.
Result proves that PVPFRST improves effectiveness and efficiency in
identifying e-learners styles and increases the performance by 27%, 22% and
25% in terms of discrimination rate, precision and recall value than the

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

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

by Smitha J.A, N. Rajkumar
Abstract: The vehicle detection system plays an essential role in the traffic
video surveillance system. Video communication of these traffic cameras over
real-world limited bandwidth networks can frequently suffer network
congestion. The objective of this paper is to develop an effective method for
moving vehicle detection problems that can find high quality solutions (with
respect to detection accuracy) at a high convergence speed. To achieve this
objective, we propose a method that hybridises the cuckoo search (CS) with
Opposition-based learning (OBL), where OBL is improve the performance of
the CS algorithm while optimising the weights of the standard PNN model. The
proposed system mainly consists of two modules such as: 1) design novel
OCS-PNN model; 2) moving vehicle detection using OCS-PNN model. The
algorithm is tested on three standard video dataset. For instance, the proposed
method achieved the maximum precision of 94%, F-measure of 94% and
similarity of 94%.

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.

KNOWLEDGE TRANSFER FOR EFFICIENT CROSS DOMAIN RANKING USING ADARANK ALGORITHM
by Geetha Narayanan, P.T. Vanathi
Abstract: Learning-to-rank has been an exciting topic of research exclusively
in hypothetical and the productions in the information retrieval practices.
Usually, in the learning-based ranking procedures, it is expected the training
and testing data are recovered from the identical data delivery. However those
existing research methods do not work well in case of multiple documents
retrieved from the cross domains (different domains). In this case ranking of
documents would be more difficult where the contents are described in multiple
documents from different cross domains. The main goal of this research
method is to rank the documents gathered from the multiple domains with
improved learning rate by learning features from different domains. The feature
level information allocation and instance level information relocation are
achieved with four learners namely RankNet, ranking support vector machine
(SVM), RankBoost and AdaRank. The estimation results presented that the
AdaRank algorithm achieves good performance.

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

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

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

Brain Tumour Detection using Self-Adaptive Learning PSO-Based Feature Selection Algorithm in MRI images
by A.R. Kavitha, C. Chellamuthu
Abstract: In this paper, we propose a brain tumour classification scheme to classify the breast tissues as normal or abnormal. At first, we segment the region of interest (ROI) from the medical image using modified region growing algorithm (MRGA). Feature matrix is generated using gray-level co-occurrence matrix (GLCM) to the entire detailed coefficient from 2D-DWT of the region of interest (ROI). To derive the relevant features from the feature matrix, we take the self-learning particle swarm optimisation (SLPSO) algorithm. In SLPSO, four upgrading strategies are utilised to adaptively redesign the velocity of every particle to guarantee its differences and robustness. The relevant features are used in a feed forward neural network (FFNN) classifier for classification. The method yield very encouraging result in terms of classification accuracy using a neural network. In experimental result most cases, the classification accuracy improved on previously reported results.

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.

Data Cubes Retrieval and Design in OLAP Systems: From Query Analysis to Visualisation Tool
by Rahma Djiroun, Kamel Boukhalfa, Zaia Alimazighi
Abstract: Business intelligence systems provide an effective solution from large volumes of data for multidimensional online computing and analysis. Usually, in a decision-making process, organisations and enterprises, require several internal and/or external cubes which are often heterogeneous. Most of the time, the structure of these cubes is unknown to the decision-makers. To analyse a phenomenon, the decision-maker seeks among sets of cubes, in a collection, the cube which responds better to his need. In this context, we propose an approach that enables decision-makers to express their needs via a query expressed in a natural language, returns top-K relevant cubes and designs/constructs new cubes when no, or few deployed cubes are relevant. We propose a tool called RD-cubes-query implementing our approach in a ROLAP architecture. We use this tool in some experiments to validate our approach.

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%.

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.
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.
Keywords: Fuzzy recommendation system; degree of similarity measure; rating factor importance; collective expert rating.
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.
Keywords: Decision tree classifier; multi-class classification; university single rate tuition fee system.
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.
Keywords: common neighbours; complex network; link prediction.

A Technique for Semantic Annotation and Retrieval of E-Learning Objects
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.
Keywords: e-learning; document clustering; balanced mutual information; one way matching; cluster based matching.

Abstract: Web pages are heterogeneous and complex and there exists complicated associations within one web pages and linking to the others. The high interactions between terms in pages demonstrate vague and ambiguous meanings. Efficient and effective clustering methods are needed to discover latent and coherent meanings in context are necessary. This paper proposes an efficient clustering approach for fair semantic web content retrieval based on tri-level ontology construction model with hybrid dragonfly algorithm. Initially the query processing phase, by making use of systematic adaptive hierarchy method (SAHM) efficient ontology selection process is carried out by means of matching keywords retrieved form user query.

Stability analysis of Feature Ranking Techniques in the presence of noise: A comparative study
by Milad Dehghani, Mojtaba Khorram Niaki, 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.

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.

Estimation of coffee rust infection and growth through two-level classifier ensembles based on expert knowledge
by David Camilo Corrales, Emmanuel Lasso, Apolinar Figueroa Casas, Agapito Ledezma, Juan Carlos Corrales
Abstract: Rust is a disease that leads to considerable losses in the worldwide coffee industry. There are many contributing factors to the onset of coffee rust, e.g., crop management decisions and the prevailing weather. In Colombia the coffee production has been considerably reduced by 31% on average during the epidemic years compared with 2007. Recent research efforts focus on detection of disease incidence using computer science techniques such as supervised learning algorithms. However, a number of different authors demonstrate that results are not sufficiently accurate using a single classifier. Authors in the computer field propose alternatives for this problem, making use of techniques that combine classifier results. Nevertheless, the traditional approaches have a limited performance due to dataset absence. Therefore, we proposed two-level classifier ensembles for coffee rust infection and growth estimation in Colombian crops, based on expert knowledge.

Behaviour-based analysis of tourism demand in Egypt
by Taheya H. Ahmed, Mervat Abu-Elkheir, Ahmed Abou Elfetouh Saleh
Abstract: Tourism demand is the total number of persons who travel, or wish to travel, to use tourists' facilities and services at places away from their places of work or residence. Analysis of tourism demand helps companies understand tourists' needs and improves their marketing strategies. Current research for predicting tourism demand is targeted at foreign countries, and the little research targeted at predicting tourism demand in Egypt is based on macro forecasting and not on understanding the collective behaviour of tourists. In this paper, we devise different granularities from tourist data that we collect and use these different granularities to provide different levels of demand prediction. We develop a hybrid prediction framework to analyse tourists' behaviour and infer behaviour rules. These rules will act as recommendations that help to understand tourists' behaviour and their needs, and define future policies regarding tourism in Egypt.

The optimal price function is achieved with the goal programming model. The price function which is described as the sum of the individual objectives (criteria), and the goals are the prices of comparable properties. The model integrates with the inductive and deductive approach overcomes many of the assumptions of the best known statistical approaches. The evaluation of the proposed model is performed by comparing the results obtained by the application, to the same case study, of a multiple linear regression model and a nonlinear regression method based on penalised spline smoothing model. The comparison shows, first of all, the best interpretation capabilities of the proposed model.

Haphazard, enhanced haphazard and personalised anonymisation for privacy preserving data mining on sensitive data sources
by M. Prakash, G. Singaravel
Abstract: Privacy preserving data mining is a fast growing new era of research due to recent advancements in information, data mining, communications and security technologies. Government agencies and many other non-governmental organisations often need to publish sensitive data that contain information about individuals. The important problem is publishing data about individuals without revealing sensitive information about them. A breach in the security of a sensitive data may expose the private information of an individual, or the interception of a private communication may compromise the security of a sensitive data. The objective of the research is to publish data without revealing the sensitive information of individuals, at the same time the miner need to discover non-sensitive knowledge. To achieve the above objective, haphazard anonymisation, enhanced haphazard anonymisation and personalised anonymisation are proposed for privacy and utility preservation. The performances are evaluated based on vulnerability to attacks, efficiency and data utility.

Information graph-based creation of parallel queries for databases
by Yulia Shichkina, Dmitry Gushchanskiy, Alexander Degtyarev
Abstract: The article describes the query parallelisation method that takes into account the dependencies between operations in the data query. The method is based on the representation of the query as a directed graph with vertices as operations and edges as data connections. The graph is processed as an adjacency list, saving more memory than during processing a sparse adjacency matrix. The graph is modified only by operations, which do not change the elements of the adjacency list. Therefore it is possible to achieve intra-query parallelism by consideration of a request structure and implementation of mathematical methods of parallel calculations for its equivalent transformation. This article also presents an example of complex query parallelisation and describes applicability of the graph theory and methods of parallel computing both for query parallelisation and optimisation.
