  1. SOTA star awarded to ActiNet, 0.860

  2. 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 CAPTURE-24, measured by Cohen’s κ (e.g. sleep staging) (higher is better). Each number is copied from the publication cited in its row, and ranks apply only within this dataset and metric and this protocol group.

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.

Evaluation protocol: Activity intensity, 4 classes (Walmsley: sleep / sedentary / light / MVPA).

Human activity recognition (IMU): CAPTURE-24, Cohen’s κ (e.g. sleep staging). Reported rankings; evaluation protocols may differ.
