Cosine item similarity implementation
-------------------------------------
Key: MAHOUT-387
URL: https://issues.apache.org/jira/browse/MAHOUT-387
Project: Mahout
Issue Type: New Feature
Components: Collaborative Filtering
Reporter: Sebastian Schelter
Attachments: MAHOUT-387.patch
I needed to compute the cosine similarity between two items when running
org.apache.mahout.cf.taste.hadoop.pseudo.RecommenderJob, I couldn't find an
implementation (did I overlook it maybe?) so I created my own. I want to share
it here, in case you find it useful.
