Sebastian Schelter updated MAHOUT-1464:
---------------------------------------
Description:
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.
was:
Create a version of RowSimilarityJob that runs on Spark. Ssc has a prototype
here: https://gist.github.com/sscdotopen/8314254. 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 which is a feature request for
RSJ on two inputs to calculate the similarity of rows of one DRM with those of
another. This cross-similarity has several applications including cross-action
recommendations.
