Results

We are pleased to present the final results of the FOMO26 Challenge. The tables include every ranked team in Track 1 (Methods) and Track 2 (Open) across all seven downstream tasks.

Ranking: Lower ranks are better. The weighted average uses 25% each for Tasks 2 and 4, and 10% each for Tasks 1, 3, 5, 6, and 7.

Teams with the same weighted average share a placement; subsequent placements follow standard competition ranking. For multi-metric tasks, the task rank is the average of the metric-specific ranks. A dash indicates no valid submission for the task.

Track 1: Methods

Models pretrained on FOMO300k.
