ProAct-75 - Step Detection: leaderboard
Metric: Step detection macro-F1 (%, 0-100) over the annotated step classes (class-averaged, long-tail sensitive); ProAct-75 best-view test split (516 videos across 75 assistance, maintenance and safety-monitoring tasks; 5-keyframe sliding windows, stride 3); zero-shot two-stage protocol: the model decides trigger and task from the window and the task list, then, if triggered, the current step and future steps from the task graph; nucleus sampling at temperature 0.7; higher is better. Source: arxiv.org. Saturation forecast: Around 2028. 9 models tracked.
