“…Not only comparing the performance of the proposed methods, but also investigating whether feature selection may further improve the results. In detail, the features chosen by our proposed method are 3,6,9,10,11,13,18,19,21,22,23,26,27,29,30,32,35,36,38, and 39, a total of 20 features. And the optimal parameters of SVM, C and γ obtained from our experiment, are (219, 28).…”
