Artifacts
What each model built on each task, shown on the held-out cases it was graded on.
Earthquake relocation
Each model relocated a month of synthetic earthquakes (500 events) from 16 stations' picks and waveforms, and the reward is computed against their hidden true positions. Shown are 60 of those graded hidden events, picked at random: the starter's locations, each model's best and median attempt, and a line from every relocated event to where it really was.
