This paper parallelizes the spatial pyramid match kernel (SPK) implementation. SPK is one of the most usable kernel methods, along with support vector machine classifier, with high accuracy in object recognition. MATLAB parallel computing toolbox has been used to parallelize SPK. In this implementation, MATLAB Message Passing Interface (MPI) functions and features included in the toolbox help u...

In this article a classification method is proposed where data is first preprocessed using new nonlinear fuzzy robust principal component analysis (NFRPCA) algorithm to get data into more feasible form. After this preprocessing step the similarity classifier is then used for the actual classification. The procedure was tested for dermatology, hepatitis and liver-disorder data. Results were quit...

K nearest neighbor classifier (K-NN) is widely discussed and applied in pattern recognition and machine learning, however, as a similar lazy classifier using local information for recognizing a new test, neighborhood classifier, few literatures are reported on. In this paper, we introduce neighborhood rough set model as a uniform framework to understand and implement neighborhood classifiers. T...

This paper describes the pattern recognition technique based on multiscale discrete wavelet transform(MDWT) and least square support vector machine (LS-SVM) for the classification of EEG signals. The different statistical features are extracted from each EEG signal corresponding to various seizer and nonsiezer brain functions, using MDWT. Further these sets of features are fed to the LS-SVM mul...

In many classifier systems, the classifier strength parameter serves as a predictor of future payoff and as the classifier’s fitness for the genetic algorithm. We investigate a classifier system, XCS, in which each classifier maintains a prediction of expected payoff, but the classifier’s fitness is given by a measure of the prediction’s accuracy. The system executes the genetic algorithm in ni...

Classification and regression are the major applications of machine learning algorithms which widely used to solve problems in numerous domains engineering computer science. Different classifiers based on optimization decision tree have been proposed, however, it is still evolving over time. This paper presents a novel robust classifier tabu search algorithms, respectively. In aim improving per...
