[jira] [Updated] (MAHOUT-1464) Cooccurrence Analysis on Spark

     [ https://issues.apache.org/jira/browse/MAHOUT-1464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

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.
