CV~LB Correlation
Notebooks Ā· 29 Apr 2024, 17:31 Ā· 5

Hello fellow competitors,

Shall we share our CV and LB scores? In my case, I'm quite confused about the correlation between the two. I have models with a CV of 0.15 but an LB of 0.22. Currently, my best LB score is 20.15, with a CV of 18.90.

Sometimes, when I add a feature that significantly decreases my CV, it negatively impacts my LB. Has anyone else experienced this in the current competition?

We are probably using the wrong approach

for sure ..it's actually crazy that you cracked the 20 score, I'm struggling to get there , maybe I'm missing something I don't know

Actually, getting a score of 25 is extremely simple. Once you reach that, you find your way to 20. What I find very difficult and confusing is going below 20
