TL;DR

MIT training code for a lightweight 1-D CNN that predicts SBP/DBP from a single PPG channel on PulseDB VitalDBTrainSubset, with a normalized Smooth-L1 objective that up-weights hypertensive label regions (SBP≥140 or DBP≥90, default weight 5). Also supports ERM and SBP-/DBP-only region definitions. No peer-reviewed venue or reported metrics found at carding; code ships architecture, config, and train script only.

  • Form factor: clinical finger/perioperative (PulseDB VitalDB Train Subset)
