Samsung wants to convert your Galaxy Watch heart data into ECGs using GenAI

A patent shows a new plan to convert PPG data into ECG data using a behind-the-scenes AI process on Galaxy Watches.

Samsung got FDA approval for passive detection of irregular heart rhythm using Galaxy Watches last year, and Fitbit, Apple, and Withings do the same. It plans to solve this by "incorporating prior knowledge in terms of probabilistic graphical models" so that it is "robust to noise," aka irrelevant or misleading information. Beyond that, Samsung's patent is far too technical for a layman to parse reasonably, with in-depth equations showing the correlation between PPG and ECG data.
