Effect of Outlier Detection on Clustering Accuracy and Computation Time of CHB K-Means Algorithm

Data clustering is one of the major areas of research in data mining. Of late, high dimensionality dataset is becoming popular because of the generation of huge volumes of data. Among the traditional partitional clustering algorithms, the bisecting K-Means is one of the most widely used for high dimensional dataset. But the performance degrades as the dimensionality increases. Also, the task of selection of cluster for further bisection is a challenging one. To overcome these drawbacks, we incorporate two constraints namely, stability-based measure and Mean Square Error (MSE) on the novel partitional clustering method, CHB-K-Means algorithm. In the experimental analysis, the performance is analyzed with respect to computation time and clustering accuracy as the number of outliers detected varies. We infer that an average clustering accuracy of 75 % has been achieved and the computation time taken for cluster formation also decreases as more number of outliers is detected.

A Pragmatic Delineation on Cache Bypass Algorithm in Last-Level Cache (LLC)

Last-level cache is a high level cache memory shared by all core in a multi-core chip to improve the overall efficiency of modern processors. Most of the cache management policies are based on the residency of the cache block, access time, frequency tour, recency and reuse distance to lower down the total miss count. However, in a contemporary multi level cache processor a bypass replacement reduces both miss penalty and processor stall cycles to accelerate the overall performance. This paper has analyzed different bypass replacement approaches. It also gives motivation behind different bypass replacement techniques, used in the last-level cache with inclusive and non-inclusive behavior with improved placement and promotion.

Effect of Physiochemical Properties on Classification Algorithms for Kinases Family

Kinase phosphorylates specific substrates by transferring phosphate from ATP. These are important targets for the treatment of various neurological disorders, drug addiction and cancer. To organize the kinases diversity and to compare distantly related sequences it is important to classify kinases with high precision. In this study we made an attempt to classify kinases using four different classification algorithms with three different physiochemical features. Our results suggest that Random Forest gives an average precision of 0.99 for classification of kinases; and when amphiphilic pseudo amino acid composition was used as feature, the precision of the classifier was much higher than compared to amino acid composition and dipeptide composition. Hence, Random forest with amphiphilic pseudo amino acid composition is the best combination to achieve classification of kinases with high precision. Further the same can be extended for subfamilies, which can give more insight into the predominant features specific to kinases subfamilies.

A Fuzzy Knowledge Based Sensor Node Appraisal Technique for Fault Tolerant Data Aggregation in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) have a wide range of applications in the real world. They consist of a large number of small, inexpensive, limited energy and low-cost sensor nodes which are deployed in vast geographical areas for remote sensing and monitoring operations. The sensor nodes are mostly deployed in harsh environments and unattended setups. They are prone to failure due to battery depletion, low-cost design or malfunctioning of some components. The paper proposes a two-level fuzzy knowledge based sensor node appraisal technique (NAT) in which the cluster head (CH) assesses the health status of each non-cluster head (NCH) node by the application of fuzzy rules and challenge-response technique. The CH then aggregates data from only the healthy NCHs and forwards it to the base station. It is a pro-active approach which prevents faulty data from reaching the base station. The simulation is carried out with injected NCH faults at a specified rate. The simulation results show that the proposed NAT technique can significantly improve the throughput, network lifetime and quality of service (QoS) provided by WSNs.

Performance Evaluation of Rule Learning Classifiers in Anomaly Based Intrusion Detection

Intrusion Detection Systems (IDS) are intended to protect computer networks from malicious users. Several data mining techniques have been used to build intrusion detection models for analyzing anomalous behavior of network users. However, the performance of such techniques largely depends on their ability to analyze intrusion data and raise alarm whenever suspicious activities are observed. In this paper, some rule based classification techniques, viz., Decision Table, DTNB, NNGE, JRip, and RIDOR have been applied to build intrusion detection models. Further, in order to improve the performance of the classifiers, six rank based feature selection methods, viz., Chi squared attribute evaluator, One-R, Relief-F, information Gain, Gain Ratio, and Symmetrical Uncertainty have been employed to select the most relevant features. Performance of different combinations of classifiers and feature selection techniques have been studied using a set of performance criteria, viz., accuracy, precision, detection rate, false alarm rate, and efficiency.

Evaluation of Faculty Performance in Education System Using Classification Technique in Opinion Mining Based on GPU

Large amount of data is available in the form of reviews, opinions, feedbacks, remarks, observations, comments, explanations and clarifications. In Education system, main focus is given to quality of teaching. That quality depends on coordination among teacher and student. Feedback analysis is more important to measure the faculty performance. Performance of faculty should be evaluated so that we can enhance our education quality. To measure the performance of faculty, we use classification technique by using opinion mining. We also use this technique on GPU architecture using CUDA-C programming to evaluate performance of a faculty in very less time.

Signature Verification Using Rough Set Theory Based Feature Selection

An offline signature verification system based on feature extraction from signature images is introduced. Varieties of features such as geometric features, topological features and statistical features are extracted from signature images using Gabor filter technique. As all the features are not relevant, only the salient features are selected from the extracted one by a Rough Set Theory based reduct generation technique. Thus only the relevant features of the signatures are retained to reduce the dimension of feature vector so as to reduce the computation time and are used for offline signature verification. The experimental results are expressed using few parameters such as False Rejection Rate (FRR), False Acceptance Rate (FAR).

Weighted Matrix Based Reversible Data Hiding Scheme Using Image Interpolation

In this paper, we introduce a new high payload reversible data hiding scheme using weighted matrix. First, we enlarged the size of original image by interpolation. Then we perform modular sum of entry-wise multiplication with original image block and predefine weighted matrix. We subtract the modular sum from secret data and store the positional value by modifying three least significant bits of interleaved pixel. The original pixels are not affected during data embedding which assures reversibility. The proposed scheme provides average embedding payload 2.97 bits per pixel (bpp) and PSNR 37.97 dB. We compare our scheme with other state-of-the-art methods and obtain reasonably better results. Finally, we have tested our scheme through some attacks and security analysis which gives promising results.

Heart Disease Prediction System Evaluation Using C4.5 Rules and Partial Tree

Cardiovascular disease (CVD) is a big reason of morbidity and mortality in the current living style. Identification of Cardiovascular disease is an important but a complex task that needs to be performed very minutely and accurately and the correct automation would be very desirable. Every human being cannot be equally skilful and so as doctors. All doctors cannot be equally skilled in every sub specialty and at many places we don’t have skilled and specialist doctors available easily. An automated system in medical diagnosis would enhance medical care and it can also reduce costs. In this study, we have designed a system that can efficiently discover the rules to predict the risk level of patients based on the given parameter about their health. Then we evaluate and compare this system using C45 rules and partial tree. The performance of the system is evaluated in terms of different parameter like rules generated, classification accuracy, classification error, global classification error and the experimental results shows that the system has great potential in predicting the heart disease risk level more efficiently.

A New Approach to Fuzzy Soft Set Theory and Its Application in Decision Making

Soft set theory is a new mathematical approach to vagueness introduced by Molodtsov. This is a parameterized family of subsets defined over a universal set associated with a set of parameters. In this paper, we define membership function for fuzzy soft sets. Like the soft sets, fuzzy soft set is a notion which allows fuzziness over a soft set model. So far, more than one attempt has been made to define this concept. Maji et al. defined fuzzy soft sets and several operations on them. In this paper we followed the definition of soft sets provided by Tripathy et al. through characteristic functions in 2015. Many related concepts like complement of a fuzzy soft set, null fuzzy soft set, absolute fuzzy soft set, intersection of fuzzy soft sets and union of fuzzy soft sets are redefined. We provide an application of fuzzy soft sets in decision making which substantially improve and is more realistic than the algorithm proposed earlier by Maji et al.

Decrease in False Assumption for Detection Using Digital Mammography

Our research work elaborated in the design and construction of a method that bring sustenance for a reduction in false assumptions during the detection of breast cancer. Our key drive of this research work was to elude the false assumptions in the detection practice in a cost effective manner. We proposed a unique method to decrease false assumption in breast cancer detection cases and split this method in three different modules as preprocessing, formation of homogeneous blocks and color quantization. The preprocessing convoluted in eradicating the extraneous slices. The formation homogeneous blocks sub-method was to do segmentation of the image. The task of the third sub-method (i.e. color quantization) was to break the colors amid different regions.

Test Case Prioritization Using Association Rule Mining and Business Criticality Test Value

Regression Testing plays a vital role for the improvement in quality of product during software maintenance phase. This phase ensures that modification made to the system under test doesn’t adversely affect the performance of the existing features. Hence regression testing incurs more cost and time. Test case prioritization, which is one of the techniques of regression testing, is an efficient technique to minimize the cost and time of testing. In this paper, the author has proposed an approach for test case prioritization by maintaining information of previous and current release of the project in a repository. To represent the behavioral aspect of the system, it is modeled using both UML activity and sequence diagram. Then frequent pattern is generated by applying Association Rule Mining on the information stored in the repository. Finally the prioritization is carried out using the generated frequent patterns and Business Criticality Value of the different features.

Nearest Neighbour with Priority Based Recommendation Approach to Group Recommender System

Group Recommender System is one of the categories of recommender system, where the recommendation of things is for a group of users rather than for any individual. These system combines the preferences of each user present in the group and then predicts things which are suitable for the users of the group. Various grouping strategies are available, which are used to generate to group recommendations, but most of them are suitable when used for specific purpose only. In this paper we have proposed a novel approach to group recommender system using collaborative filtering technique, which can be applicable to all the real world scenarios where the data set uses rating system to distinguish among users’ preferences. We have made use of nearest neighbor algorithm to create a group of users with similar likeness. We have also applied the priority among users of the group as there are some members whose preferences might affect the whole group. We have validated our results with the movie lens data set which is the standard data set for recommender system testing.

Modified Firefly Algorithm (MFA) Based Vector Quantization for Image Compression

Firefly algorithm optimization is based on the attractiveness/brightness of the firefly. In firefly algorithm, a lighter (lesser fitness function) firefly move towards the brighter firefly (higher fitness function) with amplitude proportional to Euclidean distance between the lighter and brighter firefly. If no such brighter firefly is found then it moves randomly is search space. This random move causes chance of decrement in brightness of the brighter firefly depending on the direction in which it is move. We proposed a modified firefly algorithm in which movement of brighter fireflies is towards the direction of brightness instead of random move. If this direction of brightness is not in the process then firefly is in same position. We call this novel algorithm as MFA-LBG. Experimental results shows that modified firefly algorithm reconstructed image quality and fitness function value is better than the standard firefly algorithm (FA-LBG) and LBG algorithms. It is observed that that modified firefly algorithm convergence time is less than the standard firefly algorithm.

Opposition-Based GA Learning of Artificial Neural Networks for Financial Time Series Forecasting

Artificial neural network (ANN) based forecasting models have been established their efficiencies with improved accuracies over conventional models. Evolutionary algorithms (EA) are used most frequently by the researchers to train ANN models. Population initialization of EA can affect the convergence rate as well as the quality of optimal solution. Random population initialization of EAs is the most commonly used technique to generate candidate solutions. This paper presents an opposition-based genetic algorithm (OBGA) learning to generate initial candidate solutions for ANN based forecasting models. The present approach is based on the concept that, it is better to begin with some fitter candidate solutions when no a priori information about the solution is available. In this study both GA and OBGA optimizations are used to optimize the parameters of a multilayer perceptron (MLP) separately. The efficiencies of these methods are evaluated on forecasting the daily closing prices of some fast growing stock indices. Extensive simulation studies reveal that OBGA method outperforms other with better accuracies and convergence speed.

Evolving Low Complex Higher Order Neural Network Based Classifiers for Medical Data Classification

Multilayer neural network based classifiers have been proven their better approximation and generalization ability in medical data classification. However they are characterize with both computational and structural complexities. This article proposes an Evolving Functional Link Network (EFLN) for medical data classification. First, the input signals are mapped from lower to higher dimensional feature space applying some trigonometric expansion functions. Then the optimal number of expanded input signals, weight vectors and network parameters are obtained by an evolutionary search technique. Therefore the optimal network structure can be achieved on fly by evolving a set of FLNs during training rather fixing it earlier. The proposed EFLN classifiers are validated with some benchmark data sets from UCI machine learning repository. The performances are compared with that of a gradient descent based FLN (GDFLN), multiple linear regressions (MLR) and a multilayer perceptron (MLP) and found to be superior.

Analysis of ECG Signals Using Advanced Wavelet Filtering Approach

Electrocardiogram signal is principally used for the interpretation and assessment of heart’s condition. The main criteria in ECG signal analysis is interpretation of QRS complex and obtaining its feature information. R wave is the most significant segment of this QRS complex, which has a prominent role in finding HRV (Heart Rate Variability) features and in determining its characteristic features. This paper intends to propose a novel approach for the analysis of ECG signals. The ECG signal is preprocessed using stationary wavelet transform (SWT) with interval dependent thresholding integrated with the wiener filter and is then subjected to Hilbert transform along with a window to enhance the presence of QRS complexes, to detect R-Peaks by setting a threshold. The proposed algorithm is validated with different parameters like Sensitivity, +Predictivity and Accuracy. The proposed method yields promising results with 99.94 % Sensitivity, 99.92 % +Predictivity, 99.87 % Accuracy. Finally the proposed method is compared with other methods to show the efficiency of the proposed technique for the analysis of ECG Signal.

The computation speed is restricted with the binary number system by generation and transmission particularly for the carry, as the bit size increments. Using a quaternary Signed Digit number system one may achieve an adder, subtraction which can be of carry free, borrow free respectively for multiplication. However QSD number system necessitates a different set of major modulo based logic aspects for every arithmetic operation. QSD is a superior radix number system, which is used for every arithmetic operation with generate carry free operation and the number scope for QSD is −3 to 3. Proposed QSD multipliers with generating partial products which perform very high speed operation as compared to QSD adders and also used for number of times addition process increasing. The addition process is a carry free operation and other processes for the digits of large numbers like 126,256 or further can be exerted with persistent delay and low difficulty. Tools Modelsim 6.0, Microwind are used.

Mathematical Model for Optimization of Perishable Resources with Uniform Decay

Waste stemmed from inappropriate management is a major challenge for perishable resources. Improvement of the inappropriate management has great potential to improve the efficiency of the resources. This research aims to maximize profit and reduce resource spoilage through a fitness value approach based on the decay rate of the perishable resources. A particular type of resource whose decay rate is uniform with time is considered here and is defined as uniform perishable resource. But here in this paper it is shown that the best way to utilize those resources is to follow the first method (i.e. to pick up the best resource first).

Server Consolidation with Minimal SLA Violations

Cloud computing is very promising technology to deliver computing resources like infrastructure (IaaS), platform (PaaS), software (SaaS) etc. in form of services over the Internet. Server consolidation is the mechanism to minimize active (running) physical servers in the data center of cloud service provider. Consolidation helps the service provider to make efficient usage data center resources and in turn to minimize running cost of data center. Users have to pay as per service usage. SLA is like contract between cloud service provider and users. Service Level Agreement (SLA) is the mechanism of providing guaranteed services to cloud users. SLA Violation may cause high penalties to service provider. In this paper it is shown that if consolidation is maximized, it may cause more number of SLA violation. A balanced approach of server consolidation with minimal SLA violations is suggested in this paper.

Predicting Consumer Loads for Improved Power Scheduling in Smart Homes

Smart homes form one of the major components leveraging demand response within the smart grid paradigm. Flexible pricing policies along with the capability of scheduling power among many homes form the crux of a wide variety of smart home power management controllers. However leveraging power scheduling for smart homes while keeping user costs minimal is a challenging proposition and involves complex multistage, stochastic, non-linear optimization techniques. For ease of computation, heuristic algorithms can be employed that require consumer load corresponding to smart homes which are not available a priori. The efficiency of power scheduling heuristics, however depend on the accuracy of the consumer loads forecasted. In this paper, we focus on developing a technique that can efficiently forecast consumer loads and thereafter the predicted load is fed to a GA heuristic based power scheduling algorithm for smart homes. Detailed procedure for the aforementioned forecasting has been presented and the results obtained are analyzed.

Prevention of Wormhole Attack Using Identity Based Signature Scheme in MANET

Mobile ad hoc network (MANET) has attracted many security attacks due to its characteristics of dynamic topology, limited resources and decentralize monitoring. One of these vulnerable attack is wormhole in which two or more malicious nodes form a tunnel like structure to relay packets among themselves. This type of attack may cause selective forwarding, fabrication and alteration of packets being sent. In this paper, we have proposed a way to protect network from wormhole attack by using identity based signature scheme on cluster based ad hoc network. Proposed scheme does not require distribution of any certificate among the nodes so it decreases computation overhead. We have also discussed existing work that either require certifcates or does not accomplish all the security requirements of network. Our simulation results show that attack is prevented successfully and it outperforms other schemes.

Surface Grinding Process Optimization Using Jaya Algorithm

Optimization problem of an important traditional machining process namely surface grinding is considered in this work. The performance of machining processes in terms of cost, quality of the products and sustainability of the process is largely influenced by its process parameters. Thus, choice of the best (optimal) combination machining parameters is vital for any machining process. Hence, in present work a new algorithm is used for solving the considered optimization problem. The Jaya algorithm is a simple yet powerful algorithm and is a algorithm-specific parameter-less algorithm. The comparison of results of optimization show that the results of Jaya algorithm are better than the results reported by previous researchers using GA, SA, ABC, HS, PSO, ACO and TLBO.

BITSMSSC: Brain Image Tomography Using SOM with Multi SVM Sigmoid Classifier

Image segmentation is a process of elevating the objects by partitioning a digital image into multiple segments. To analyze an image, segmentation is the best process to follow. Especially, for detecting tumours from medical images such as brain, skin and breast in the field of medicine. To improve the results of brain images PSNR, ENTROPY image fusion technique is applied. Here the segmentation process is carried out by k-means clustered model algorithm. Then the entire data base is subjecting to classification mode under multi class svm sigmoid classifier. This generates a descent output of 96 % accurate results using various texture features they are contrast, energy, area of the tumour detecting by the cluster model and entropy. These parameters helps in identifying the tumour detection from brain MRI, CT scanned images.
