Sebastian Schelter updated MAHOUT-1464:
---------------------------------------
Attachment: MAHOUT-1464.patch
Updated patch. Removed the similarity form of LLR, removed math specific code
that was adressed in MAHOUT-1508, added nicer output and did a few cosmetic
changes.
I think this code is ready to be tested on a cluster, does anybody have time
for that?

> Create a version of Cooccurrence Analysis (RowSimilarityJob with LLR) that
> runs on Spark. This should be compatible with Mahout Spark DRM DSL so a DRM
> can be used as input.
> Ideally this would extend to cover MAHOUT-1422. This cross-cooccurrence has
> several applications including cross-action recommendations.
