@ptrblck yes all features are much overlapped for binary classification , there is no specific overlapped region where they are overlapped, class 1 and class 0 both are over lapped with 50/50 ratio in all region for all features. I created density plot of all features for class 1 vs class 0 , they are much overlapped so you cant identify which kde is for class 1 and which one is for class 0. Any idea to handle this situation?
