Ted Dunning commented on MAHOUT-525:
------------------------------------
The LLL recommender is almost more of a classifier and is still way out in
left-field relative to the existing recommender framework.
It would be great to start integrating it, but it probably should be made to
work well first.

> Issue Type: New Feature
> Reporter: Ted Dunning
> Fix For: 0.5

> The approach is based on the paper http://arxiv.org/abs/1006.2156
> For integration into Mahout, the idea would be to build an OnlineLearner that
> accept feature vectors where the first two elements are assumed to be the row
