I see the leaderboard positions are still changing, what does this mean and how long it is expected to saturate after

?

Maybe still arranging according to the your selected submissions?

Congratulations Belal_Emad

Was your choice of submission 6.09 because of robustness of cross validation?

Thank you!

The submission 6.09 is my best on public leaderboard without postprocessing, so I chose a submission with post processing and a submission without, my CV results were almost the same so I chose according to the public

My CV didn't change much either, in fact it was very difficult to get anything consistent, so I had to use as many submissions as I had.

I ended up making a similar choice, a more aggressive one with the best lb and one with a more robust model in terms of overfitting and which would have more chances in the private lb.

Thanks for the answer and congratulations on the 2nd place in the competition.
