Table 1. The performances of SVM model and RF model in classification of MFEs.

Positives Negatives TP FP TN FN SP (%) SE (%) PPV (%) Q (%)
SVM 6,782 10,714 5,642 1,435 9,279 1,140 86.6 83.2 79.7 85.3
RF 6,782 10,714 6,368 632 10,082 414 94.1 93.9 91.0 94.0

The prediction were evaluated by parameters of TP (true positive), FN (false negative), TN (true negative), FP (false positive), specificity SP =  TN/(TN+FP), sensitivity SE =  TP/(TP+FN), positive prediction value PPV = TP/ (TP+FP) and overall accuracy Q =  (TP+TN)/ (TP+FN+TN+FP).
