[jira] Commented: (MAHOUT-236) Cluster Evaluation Tools

    [ https://issues.apache.org/jira/browse/MAHOUT-236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868741#action_12868741 ] 

Jeff Eastman commented on MAHOUT-236:
-------------------------------------

The patches have all been committed and CDbw produces some numbers that, without deeper analysis, appear to be reasonable for all the algorithms. I'm inclined to close this issue unless others have concerns about this implementation's correctness, completeness, etc.
