>                 Key: MAHOUT-525
>                 URL: https://issues.apache.org/jira/browse/MAHOUT-525
>             Project: Mahout
>          Issue Type: New Feature
>    Affects Versions: 0.4, 0.5
>            Reporter: Ted Dunning
>            Assignee: Ted Dunning
>             Fix For: Backlog

> 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
> and column id's.  The learning will proceed by stochastic gradient descent.
