Participants are allowed to submit 3 submissions in a day. However, the latest two would be considered for final evaluation, and the once with the highest evaluation score would be selected for the leaderboard. The public leaderboard provides publicly visible submission scores based on a representative sample of the test data. This leaderboard is visible throughout the competition. The private leaderboard, by contrast, tracks model performance using the remainder of the test data. The private leaderboard thus has final say on whose models are best, and hence, who the winners and losers of the Competition will be. Private leaderboard score would be published after the deadline.
