Key facts

Parameters: Exported encoder ~10.76M
Venue: arXiv preprint (cs.LG), 2026-09-29

Summary

1. Duration-grounded targets: 16 classical PPG-derived supervision signals introduced when input length supports their analysis intervals (e.g. local morphology @10 s; reflected-delay + RMSSD @30 s; pNN50 / ACF / LF fraction / interval SD @240 s).
