Selecting the Optimal Combination Model of FSSVM for the Imbalance Datasets

Table 2

FSSVMs compare with SSVM and the normal SVM on five datasets for G-means (%) and time (s) (exclusive the time of the preprocessing normal SVM). All of the SSVMs are based on the BFGS algorithm and the two kinds of fuzzy membership functions and three kinds of smooth functions are used in the FSSVMs.
