Other articles did mention that this will be local.

I have a feeling they are using federated machine learning for this to have a lot of the processing done locally and not need to activate the radios for as much of the processing as possible. They have been making big strides in that area lately and this might be the start of some of the major applications of it (I think they are using it in their keyboard prediction as well from a bit ago)

so there's going to be a huge database of songs on my mobile!!! i don't think anybody asked for it... sounds like trickery... this is going to take up some storage space now...

anyone know how many gb or mb this occupies in my phone... can v jus clear this data...

[exhilaration]

The phone is just storing song fingerprints, probably no more than a few megs for every song ever recorded. It would be great to extract the data and release it for public use.

This was my thought as well. Hopefully someone extracts this database for anyone to hack on.

I doubt it, that would be a good chunk of data for what I see as a fairly small feature.

More likely (this is a guess, nobody outside google really knows at this point), they will use federated machine learning to figure out that something is "a song", then perhaps clean up and isolate the actual "song" part of it and send that over to a google server for processing.

But again it was just announced, so nobody really knows how this works, where the data is or goes, and what tradeoffs were made.

They announced, in the talk, that this is all done locally on the phone. The phone will have a database of, iirc, 10,000 songs locally.

Ah! Then I'm sure they have some way of making the data needed much smaller than I thought it could be!

[Anm]

They only need to store (and occasionally update) the kernel parameters for the trained deep neural net. Very small indeed.

how small, what technology is that?
