One account per participant You cannot sign up to Kaggle from multiple accounts and therefore you cannot submit from multiple accounts. No private sharing outside teams Privately sharing code or data outside of teams is not permitted. It's okay to share code if made available to all participants on the forums. Team Mergers Team mergers are allowed and can be performed by the team leader. In order to merge, the combined team must have a total submission count less than or equal to the maximum allowed as of the merge date. The maximum allowed is the number of submissions per day multiplied by the number of days the competition has been running. Team Limits The maximum size of a team is 3 participants. Anonymous Teams You are allowed to make your team anonymous, which hides participant details. Submission Limits You may submit a maximum of 5 entries per day. You may select up to 50 final submissions for judging. You are strongly encouraged to work in a group of three students. Groups may not collaborate with other groups. You cannot cite other teams' work. This includes sharing data, intermediate and final results, writing, or discussing your detailed method with other groups. You may not view reports from other teams until after the peer-review phase begins!
