Hello hosts -
I am curious what is the % data split for public LB vs Pvt LB? I couldn’t find this information, so wanted to clarify,
Thanks,

Thanks for asking! We are not disclosing the public/private leaderboard split for this challenge. We encourage competitors to focus on approaches that generalize well and to follow best practices to prevent overfitting.

So we have public and private LB datasets? I didn’t find details on this. Does the private LB perf determines the final scores? Or public LB perf holds some weight as well? Or are these details classified?

Hi @oknaitik - Correct, there is a private and public leaderboard. When the competition concludes, your private score will be revealed and used for final ranking.

@cszc Could you confirm if the submission associated with our best public LB score is considered as the final submission or the last one?

@oknaitik I apologize, I misspoke in my earlier post (now deleted to avoid confusion). At the end of the competition, the submission with your best _private_ score is selected as your final submission, and your rank is determined by that score.
