[jira] [Updated] (MAHOUT-525) Implement LatentFactorLogLinear models

     [ https://issues.apache.org/jira/browse/MAHOUT-525?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Owen updated MAHOUT-525:
-----------------------------

    Affects Version/s: 0.5
                       0.4
        Fix Version/s:     (was: 0.5)
                       0.6

May I be so bold as to move to 0.6? There's no movement since we began the call to converge on 0.5 and it's not obviously on the cusp of resolution.

> 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.
