correlation between LV and leaderboard
Data · 22 Jun 2021, 17:08 · 3

I get a 0.46 in my local validation, but in the leaderboard i get 0.2,

I need your opinion about this situation and if you have any idea about the correlation between local validation and leaderboard.

thank you all

Yes, it can be that bad. Keep working on your model. The deadline is near.

Feature engineering, cross-validation might help. Don't stack models, I don't think it helps.

One of the best strategies is to select the submission with your best leaderboard score, and the best score on your local validation.
