There is graphlab implementation of the exact ALSWR algorith.<br />Documentation is found here: http://www.graphlab.ml.cmu.edu/pmf.html<br /><br />Installation instructions for Linux: http://bickson.blogspot.com/2011/02/graphlab-large-scale-machine-learning.html<br />Installation instructions for MAC OS: http://bickson.blogspot.com/2011/02/graphlab-large-scale-machine-learning_28.html<br />You will need to install itpp/lapack.

I am quite excited since the code was just released and I am already in touch with several people who are trying it already. Any feedback is appreciated.Danny Bicksonhttps://www.blogger.com/profile/01517237836051035400noreply@blogger.com
