The top two leaderboard rankings are interesting. Rank 1: we know an F1 score greater than 1 is impossible. Rank 2: an F1 score of 0.997 is awesomely impressive! Congratulations for coming up with a crystal ball. It is also puzzling that we don’t see any F1 scores <0.4.
Hi, the bug in the leaderboard is addressed now. The change of scores from F1 as primary to Logloss as primary had created inconsistent leaderboard.
