Classification accuracy of eight feature selection methods. a - e, Maximum classification accuracy of eight feature selection methods on five datasets (CEFS+ is our proposed method, and CEFS is the basic version of CEFS+. RF, SVM and lgb stand for the classifiers Random Forest, Support Vector Machine and lightGBM respectively). f, Maximum average accuracy of eight feature selection methods on three high-dimensional gene datasets (arcene, BRCA and pancan_tcga).
