Federated learning keeps your raw data on your device while your phone trains a shared AI model locally, only sending back tiny updates rather than the full picture of your behavior. It's a genuine privacy improvement over centralized collection, but updates can still be reverse-engineered to infer sensitive details, and most companies combining federated learning with other data sources haven't actually closed all the leaks.
Federated learning is an AI training approach where machine learning models are updated using data stored locally on your device rather than sending raw personal data to a central server, keeping your information closer to home.
While federated learning is often promoted as a privacy-preserving technique, understanding its real limitations and the residual risks it carries helps you make more informed decisions about which AI-powered apps and services you choose to trust.
