- Physical activities enable scalable foundation modelling for broad-spectrum health prediction (StepFM)2026 · arXiv preprint
StepFM is a foundation model built only on step-counter data for broad health prediction. Its pretraining learns temporal and behavioural patterns from large-scale step sequences, and it transfers to more than 20 health risk tasks across devices, regions and diseases.
- Published: arXiv preprint, 2026
- Input: step counts
- Evaluation: 20+ health risk prediction tasks
