Researchers trained a health AI with 3M days of Apple Watch data

A new study by researchers from MIT and Empirical Health used 3 million person-days of Apple Watch data to develop a foundation model that predicts medical conditions with impressive accuracy. Here are the details.

A bit of background

While Yann LeCun was still Meta’s Chief AI Scientist, he proposed the Joint-Embedding Predictive Architecture, or JEPA, which essentially teaches an AI to infer the meaning of missing data rather than the data itself.
