I participated in datahack Knocktober 2016 and ended with public score 0.82(rank 14). However, my private score dropped to 0.73(rank 51). This was a kind of shock to me. I didn't expect this much difference. My model is a simple ensemble of 1 random forest and 7 XGB models. I started practicing ML from few months. I would like to hear best ways from experts to cross check this kind of overfitting to public leader board. Thanks in advance.
