Edward J. Yoon commented on HAMA-612:
-------------------------------------

Hi Buddhima,
Here's link for you: http://canini.me/research_files/OnlineCollaborativeFiltering.pdf

As you know, low-rank matrix factorization is often used as a technique for collaborative
filtering, you can use distributed stochastic gradient descent algorithm for performing low-rank
matrix factorization (on a stream of incoming examples).
