Importance score curve and the performances of k-nearest neighbor (KNN), naïve Bayes (NB), support vector machine (SVM), and random forest (RF) classifiers. a The ranked scores were calculated from five AA factors using the random forest method. The x and y coordinates denote the total length of the 11 protein alignments and the importance scores, respectively. The cutoff value 10 is indicated by the thin horizontal line. b Performances of the four classifiers were evaluated from 100 repeats of 10-fold cross-validation. The area under the curve (AUC) ranges from 0 to 1
