PulseAnchor: Personalizing PPG Foundation Models for Cuffless Blood Pressure Estimation
Vaibhav Ganatra, Kenneth Christofferson, Alex Mariakakis
Summary
Reformulates BP as relative prediction: contrast a test sample against subject-specific calibration examples from a PPG FM's embedding space. On Aurora-BP: SBP 7.84 / DBP 5.47 mmHg MAE, 15% / 22% better than existing personalization approaches. Which FM backbone and how many calibration readings aren't in the abstract.
