Dmitriy Lyubimov commented on MAHOUT-1464: ------------------------------------------ What's the best way to share PDF source? i can put it on the site so committers can re-generate it. otherwise, its source right now in my github doc branch here and pull request is definitely possible way to collaborate too: https://github.com/dlyubimov/mahout-commits/tree/ssvd-docs > RowSimilarityJob on Spark > ------------------------- > > Key: MAHOUT-1464 > URL: https://issues.apache.org/jira/browse/MAHOUT-1464 > Project: Mahout > Issue Type: Improvement > Components: Collaborative Filtering > Affects Versions: 0.9 > Environment: hadoop, spark > Reporter: Pat Ferrel > Labels: performance > Fix For: 0.9 > > Attachments: MAHOUT-1464.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
