Figure 2. The mean Acc values of the (A) Model-I and (B) Model-II models constructed by the DTC, RFC, SVC, GBC, KNC, and ANNC algorithms; the confusion matrixes of the (C) Model-I and (D) Model-II models constructed by the GBC algorithm. DTC: Decision tree classifier; RFC: random forest classifier; SVC: support vector classifier; GBC: gradient boosting classifier; KNC: k-nearest neighbor classifier; ANNC: artificial neural network classifier.
