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?
0.13...cv vs 0.32 lb
atleast yours are a bit closer😅
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
I will have to start over figure out where I am messsing up
