Historically, that meant your texts, recordings, or images were uploaded to company servers for training. But a growing body of research and real-world frameworks are changing this: a technique called federated learning, and a new refinement called Federated Constrained, now makes it possible for AI to improve itself using only the processing power on your own phone or laptop, without raw data ever leaving your device. ...
