Dmitriy Lyubimov commented on MAHOUT-376:
-----------------------------------------
i am chipping out on mapper implementation on weekends. so far i got to Q
orthogonalization, and should be able to produce BB^t at the next one.
I'll post a patch when there's something working, but it is a slow progress due
to my load. My employer at the moment is not eager to advance tasks that may
depend on this, so i have to do it on my own time.
> Implement Map-reduce version of stochastic SVD
