Cross validation scores?

Hello, do you mind sharing your methods (gbdt / neural netwok / something else) and cross validation scores?

mine is -on average- around 0.885

Hello @Belal_Emad,

First of all, it depends on the split strategy you're using. Could you please clarify which one you’re following? For us, it’s a split by location + target.

With this approach, We're currently able to reach the current LB score with 93% Accuracy and 93 F1 Macro CV Scores.

Just to confirm—did you reach the current LB score with only 88 CV? If so, I suspect there might be some overfitting to the public LB, unless you’re applying some sort of post-processing. Could you shed some light on that?

@marching_learning, @Koleshjr, @nymfree, @Abdourahamane_, @Gozie, @NogginHq, @Brainiac Would love to hear how things are going on your side in this competition!

Hello, ASSAZZIN

we can consintently get 0.96+ CV , based on a 5fold stratified KFold based on the target, but the LB keeps on fluctuating model by model by a gap of 0.01 to 0.05

@ASSAZZIN my CV is around 95 based on 10 folds stratified on the target.

Thanks @Belal_Emad, @Koleshjr, @Brainiac.

@Abdourahamane_ You raised the bar a bit higher ! It will be a sleepless weekend for some of us if you confirm it's a modeling score (Not post processing) !

Hi @ASSAZZIN , I'm not using any postprocessing for my current score , I 'm just ensembling the predictions of three powerful models trained on the satellite imagery.

My CV score is almost perfect.
