How to participate

There are 3 distinct sub-challenges. Each sub-challenge is managed through its individual Codabench page—combined results will be listed on the leaderboard here. You may participate in each separate out-of-domain challenge, or any combination of sub-challenges.

To participate in the shared challenge, use the same team name across all 3 sub-challenges. The winner of the combined challenge is determined by the smallest summed rank across the three challenges (e.g., 1st + 2nd + 4th = 7).

Winners will be announced here at the end of the challenge and invited to the winners' ceremony at the ML Challenge workshop in Spring 2026.
