CV vs Leaderboard
Help · 4 May 2019, 20:43 · 9

There is a huge gub between my CV and the leaderboard score , is there any one encountering this problem ?

Yes, I have the same problem getting 0.75 CV

I tried different approaches in order to reduce this gap but I think the test set is different from the train set

By the way, when I summed the logloss error for the predicted columns independently* my CV score was similar to the LB score. I am not sure if it's a coincidence or may be Zindi is miscalculating the error.

*sum(logloss(predicted_probability_class_i, 1 if class_i else0 ))
