SMK-NTC Random Forest Classification. a Average AUC for different number of genes are shown in this figure. The highest AUC of 0.98 is obtained using 20 genes. b Average Gini importance of genes across 50 runs of the model indicates the influence of the genes in correct classification (distinction) of SMK and NTC samples. c ROC curve associated with the model achieving the highest AUC
