Researchers have developed a new generative self-supervised learning framework called TS2TC to improve the estimation of physiological parameters from photoplethysmography (PPG) data. This framework addresses the challenge of limited annotated data by learning robust representations from large unlabeled datasets. TS2TC utilizes temporal, spectrogram, and mixed domains, along with a novel Cross-Temporal Fusion Generative Anchor (CTFGA) pretext task and a dual-process transfer (DPT) strategy, to extract both global and local contextual features. Experiments demonstrated that TS2TC achieved a 2.49% improvement in RMSE over existing methods using only 10% of the training data. AI
