A recent note on the Google AI blog discusses the company’s
use of a deep neural network for music recognition on mobile devices. As it
brings extreme-scale noodling (convolution) to bandwidth limited devices (smart
phones) it could be a breakthrough on par with MPEG and JPEG, which
dramatically transformed music distribution beginning in the 1990s. It’s known
as Now Playing, and it can use a sequence of embeddings that run your music
against its network and recognize the song, while conserving energy on the
device. Each embedding has 96 to 128 dimensions. An embedding threshold is
raised for obscure songs – which is the town where I live. I guess when you
look at what Google has done with Search, it shouldn’t be that surprising – but
the idea that so much of the work occurs on the Thing (device), is pretty
astounding. I asked it ‘what’s that song’
and it got it right. Slam dunk. “Ride Your Pony” by Lee Dorsey. Now, Shoot!
Shoot! Shoot! Shoot! Jack Vaughan
