Disclosure: I'm one of the people behind Aidlab.

If you're working on human activity recognition, exercise classification, or repetition counting, we've published AIDLAB-HAR on Hugging Face under CC BY 4.0.

It contains 180 chest-worn recordings and 518,300 samples at 50 Hz. The signals include 3-axis acceleration, orientation quaternions, 16 activity labels, and repetition markers.

We packaged it into three configurations that work directly with the datasets library: recordings, signals, and annotations. The raw v3 archive, cleaning notes, and preparation script are included too.

One detail we found while preparing the release: the paper's overview mentions 15 activities, while the archive contains 16 filename labels. We documented the discrepancy and preserved the source labels.
