ML+Hadoop at NYC Predictive Analytics

I was just at the NYC Predictive Analytics meetup talking about how we build machine learning algorithms using Hadoop to power music recommendations.

Great meetup, where we had two speakers, me and Blake Shaw from Foursquare. Blake talked about how they use machine learning at Foursquare, using Hadoop (and Luigi), and he uploaded his slides here!

Here's the full video for the talk (both mine and Blake's)
