Comparison of prediction overfitting rate of various feature selection methods. The overfitting rates of different feature selection methods PCA, Chisquare, Gradient, Gainratio, Inforgain, Relief, and SVM-RFE over three classification algorithms, LibSVM, SMO and SL were compared. The overfitting rate was calculated by the percentage of the difference between the training accuracy and prediction accuracy of the summary of both the accuracies for a specific method.
