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 ))
I tested the same idea and i get the same score like the lb
