  1. Leaderboard added with 1 result

From the hub's dated sync history: new results as they are added, and SOTA stars as they are awarded or move.

This page ranks every result ChatPPG has recorded for human activity recognition on μDPad, measured by Accuracy (higher is better). Each number is copied from the publication cited in its row, and ranks apply only within this dataset and metric.

Only one result has been reported on this dataset and metric so far, so this is a reference point rather than a multi-method comparison.
