SensorFM: Towards a general intelligence and interface for wearable health data

Google Research · 3 months ago · 50

Google researchers developed SensorFM, a foundation model trained on over one trillion minutes of unlabeled wearable sensor data from five million participants to create a general-purpose representation of human physiology. The model achieved 31% lower reconstruction loss than smaller variants and outperformed supervised baselines on 34 of 35 health prediction tasks spanning cardiovascular, metabolic, sleep, and mental health domains. This approach enables a single reusable model to adapt across diverse health outcomes rather than requiring separate bespoke models for each condition.
