Classification accuracies of reduced feature subsets using wrapper-based methods with RF, SVM, DT, KNN, LR, and GNB (NOF: number of features, IFS: initial feature set, FFS: forward feature selection, BFS: backward feature selection, EFS: exhaustive feature selection, RFE: recursive feature selection).
