Google Research Introduces SensorFM: A Wearable Health Foundation Model Pretrained on One Trillion Minutes of Sensor Data

1Key Takeaways

• SensorFM, a wearable health foundation model from Google Research, Google DeepMind, and university collaborators.
• We walk through its ViT-1D masked-autoencoder backbone, pretrained on more than one trillion minutes of unlabeled sensor signals from 5,000,000 consented participants.
• We examine the co-scaling results across four model sizes and four data volumes, including the case where capacity outruns data.
• We show how frozen embeddings plus a PCA-50 linear probe beat feature-engineered….
