Federated learning

Last year, Google introduced the ability to customize how sensitive your Smart Displays and speakers are to the hotword. Assistant is now using federated learning on Android to prevent “Hey Google” misactivations and misses.

Federated learning is not a new concept in the tech industry with Google exploring it for Gboard last year. However, ahead of I/O, the company has published a new video that provides a good recap of its benefits, possibly suggesting a broader push at tomorrow’s keynote.
