|Abstract:||In classification problems, algorithm and feature selection plays a major role. The features selected may vary the classification accuracy of different classifier algorithms. So it’s necessary to apply efficient methods of feature selection before designing the classifier. In this paper, focal and non-focal intracranial Electroencephalographic (iEEG) signal classification aided by Genetic Algorithm (GA) for optimal feature selection is proposed for Support Vector Machines (SVM), k-Nearest Neighborhood (k-NN) and Feed Forward Neural Network (FFNN) classifiers. Statistical features from raw signal and Discrete Wavelet Transforms (DWT) were extracted from iEEG signal to have pool of features from which the optimal feature sets are selected by GA. The results of each classifier were compared based on their selected features and performance estimates.|
