[jira] [Updated] (MAHOUT-910) Improve sampling in SamplingCandidateItemStrategy, optimize intersection computations

     [ https://issues.apache.org/jira/browse/MAHOUT-910?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Owen updated MAHOUT-910:
-----------------------------

    Attachment: MAHOUT-910.patch
