Figure 4

Effect of feature algorithms on the classification accuracy. The figure shows comparative prediction results for 6 feature selection methods, which include PCA, Chisquare, Gainratio, Inforgain, relief, and SVM-RFE. The prediction accuracy shown in the figure was mean values by averaging different classification algorithms including J48, LibSVM, NB, RF, SMO and SL for each feature size (10 to 500).
