- Wearable devices record physiological and behavioral signals to improve health predictions.
- Foundation models are primarily applied to low-level sensor data, but behavioral data is often more informative.
- A foundation model of behavioral signals was developed using over 2.5B hours of wearable data from 162K individuals.
- The model was evaluated on 57 health-related tasks, showing strong performance in diverse applications.
- It excels in behavior-driven tasks like sleep prediction and improves when combined with raw sensor data.
- The results highlight the importance of tailoring foundation model design to wearables for new health applications.
