Example of a recommender system with sparse data

[zachmayer]

rcv1 and mnist are both very interesting, but I'm personally most interested in vectorflow for recommendation systems.

Could you add an example of this use case? Maybe the matrix factorization example from netflix would be a place to start: https://github.com/JohnLangford/vowpal_wabbit/wiki/Matrix-factorization-example

I agree. A sample usage will be very much appreciated.

Agreed! Would love an example for matrix factorization
