Daniel Zohar commented on MAHOUT-910: ------------------------------------- I think the latest implementation looks great. It gives very fine control over the sampling. However I do have to agree with Ted. In my code, I had to create a hack for users with few items. Otherwise I would get very little to no recommendations. > Improve sampling in SamplingCandidateItemStrategy, optimize intersection > computations > ------------------------------------------------------------------------------------- > > Key: MAHOUT-910 > URL: https://issues.apache.org/jira/browse/MAHOUT-910 > Project: Mahout > Issue Type: Improvement > Components: Collaborative Filtering > Affects Versions: 0.5 > Reporter: Sean Owen > Assignee: Sean Owen > Fix For: 0.6 > > Attachments: MAHOUT-910.patch, MAHOUT-910.patch, MAHOUT-910.patch, > SamplingCandidateItemsStrategy.java > > > Per the lengthy discussion on the mailing list about optimizing > SamplingCandidateItemStrategy and related code, I'm opening this placeholder > issue. -- This message is automatically generated by JIRA.
