Contributions of AA factors and different mutation sets. a Performance of SVM classifier for different combinations of the five AA factors. The x and y coordinates denote the 31 combination patterns and the AUC values (from 0 to 1), respectively. Along the x axis, ‘15’ denotes that the set of 178 amino acid residues was transformed using AA Factor 1 and AA Factor 5 together, for example. b Contributions of mutation positions for different cutoff values (range 10–20). The y coordinate shows the AUC values
