Always trust your local cross validation they said. Congratulations to everyone who took part in this competition. It was a great learning experience.
@Koleshjr Congratulations! What type of models and cross-validation techniques did you use?
One catboost + stratifiedKFold on the target
And thank you :)
Great approach! Thank you!
Lol my Local CV gave me my beat score even thou it was good enough
Congrats 👏
A great learning experience
Always, indeed, trust your local CV. I had one with 1.028 in the private score, and I didn't choose it since it performed poorly on the public leaderboard, It has 1.030 as I am seeing it now. Congratulations to the winner. Let's meet next time.
Yeah congrats on your winning 🏅
Hope to learn about your approach
Wow thats amazing. What CV strategy did you use ? Because i never passed 1.050 in my local validation which was (stratifiedKFold)
