Hector Yee commented on MAHOUT-716:
-----------------------------------

Thanks for the review Isabel.

The git used to be at https://github.com/klout/mahout_delete

The paper it is based on is here: http://www.cs.berkeley.edu/~jduchi/projects/DuchiSi09_boost.html

I'm hesitant to make changes to it as now I would have to get google's approval to re-submit
