Why would there be a reference to it? You could have searched federated Analytics. I even made a link that does it for you. And you refuse to read. It's not my problem of you can't understand the multitude of explainations and diagrams available in the link provided for you.....Again, in general, yes. But I guess that explanation suffices, tried searching the flag (from phenotype config) on Google but didn't find any other references to it.
But I guess it can't hurt, I had federated *learning* on Gboard for like a day back in August and it made suggestions 10x better, so hopefully I see a difference
You need to learn how to troubleshoot finding information out online. If a random flag doesn't find anything how about some keywords.... You know the ones you asked the definition for?
