Persistent storage of factorizations in SVDRecommender
------------------------------------------------------
Key: MAHOUT-667
URL: https://issues.apache.org/jira/browse/MAHOUT-667
Project: Mahout
Issue Type: Improvement
Components: Collaborative Filtering
Affects Versions: 0.5
Reporter: Chris Newell
Assignee: Sean Owen
Priority: Minor
Fix For: 0.4
As discussed previously (https://issues.apache.org/jira/browse/MAHOUT-640) it
would be beneficial to provide a persistent storage mechanism for
factorizations created by SVDRecommender (in package
org.apache.mahout.cf.taste.impl.recommender.svd) as these can be time consuming
to produce. It would also allow factorizations to be computed on one machine
then distributed to other machines providing predictions, improving efficiency
and scalability.
Having a "persistence strategy" interface has been suggested that could be
implemented as required. I'll try to post a outline proposal for discussion
purposes in the next few days but any comments or suggestions would be very
welcome.
