Comparison of SVM, PCPNN, and PCRVM.

Classifier	Feature extraction	Strategy	Experiment no.	Decision threshold	Accuracies for test cases (𝐹me)
					Single-faults	Simultaneous-faults	Overall faults
SVM	WPT + TDSF + KPCA	One-versus-all	9	Not applicable because of binary outputs of SVM	0.9594	0.4546	0.7725
PCPNN	WPT + TDSF + KPCA	Pairwise coupling	10	𝜀 = 0.76	0.9198	0.7526	0.8661
PCRVM	WPT + TDSF + KPCA	Pairwise coupling	11	𝜀 = 0.67	0.9336	0.8364	0.9129
