Is there a way to find an equivalence between leaderboard & cv ? Leaderboard is giving 475 , CV is giving 500 000 even on smaller folds than the test's length. how is that possible? I'm using mean_squared_error and r² as metrics.
"The error metric for this competition is the Root Mean Squared Error", so may be you should calc root from 500000?
Yeah forgot to add the sqrt lol. Thanks a lot!
still getting 20 seconds of difference between lb/cv scores. I just wanna make sure, is it normal in case train/test are a bit different, or do i need to make a better split to have coherent cv/lb scores?
