Researchers have developed Hypnos, a new foundation model for sleep physiology that utilizes next-token prediction for representation learning. Trained on eight different sensing modalities from over 20,000 polysomnography recordings, Hypnos tokenizes physiological signals and uses an auto-regressive RQ-Transformer to predict future data points. This approach significantly outperforms existing models on various benchmarks, including sleep stage classification and atrial fibrillation detection, while requiring substantially less labeled data.
