Overview SVM performance when using set I as training positive set and set III as positive testing set and vice versa. a ROC analysis results obtained by using set I and top-set-IV as training set and one example of ran-set-III and top2-set-IV as test set; b ROC analysis results obtained by using one example of ran-set-III and top2-set-IV as training set and set I and top-set-IV as test set; c AUC values distribution of 100 ROC analysis as described in a associated with different ran-set-III sampling. c AUC values distribution of 100 ROC analysis as described in b associated with different ran-set-III sampling
