Evaluation details

IMU-Bench subject-disjoint 2.56 s, 12 classes, wrist channels only — different protocol from ZARA-family rows; not ranked against them.

Label set: 12 classes

Sensor: IMU

Body site: wrist

Sampling rate: 50 Hz

Rows are ranked only within this task × dataset × metric and one protocol group. Protocols can still differ in detail; read each method's evaluation details before comparing. Year, code, open weights and size come from each model's or paper's record; a dash or “Unknown” means the record does not say.

This page ranks every result ChatPPG has recorded for human activity recognition on MHEALTH, measured by Macro-F1 on HAR activities (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: IMU-Bench protocol: subject-disjoint splits, 2.56 s windows, baselines retrained on the same corpus.
