A robust PPG foundation model using multimodal physiological supervision
Researchers developed a PPG foundation model that leverages multimodal physiological signals (ECG and respiratory data) to improve robustness on noisy wearable data, achieving better performance than existing approaches while requiring 3x fewer training subjects. This advancement could enhance the reliability of PPG-based health monitoring in consumer devices and clinical applications.
