Collaborative filtering with GraphChi

Collaborative filtering with GraphChi by Danny Bickson.

From the post:

A couple of weeks ago I covered GraphChi by Aapo Kyrola in my blog.

Here is a quick tutorial for trying out GraphChi collaborative filtering. Currently it supports ALS (alternating least squares), SGD (stochastic gradient descent), bias-SGD (biased stochastic gradient descent) and SVD++, but I am soon going to implement several more algorithms.

If you are already experimenting with GraphChi, you will really like this post.
