[jira] [Commented] (MAHOUT-1072) FuzzyKmeansDriver emitMostLikely has no effect

Posted by "Paritosh Ranjan (JIRA)" <ji...@apache.org>.

    [ https://issues.apache.org/jira/browse/MAHOUT-1072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13461044#comment-13461044 ] 

Paritosh Ranjan commented on MAHOUT-1072:
-----------------------------------------

Now there are two parameters to control outliers, one is threshold and the other one is emitMostLikely.

If possible, I would have liked to get rid of emitMostLikely in future. So, the default should have been false in that case.

Still, since we have not removed emitMostLikely yet, so, it would be good to just pass the value provided by the user for cluster classification.

The current build is not stable, I will commit it once the build becomes stable. 

Thanks.

[jira] [Commented] (MAHOUT-1072) FuzzyKmeansDriver emitMostLikely has no effect

Posted by "Jeff Eastman (JIRA)" <ji...@apache.org>.

    [ https://issues.apache.org/jira/browse/MAHOUT-1072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13461460#comment-13461460 ] 

Jeff Eastman commented on MAHOUT-1072:
--------------------------------------

Seems to me the outlier threshold and emitMostLikely do different things:
- Outlier threshold emits only points with pdf>threshold. This is relevant for all cluster types.
- EmitMostLikely emits only the point with max(pdf) and is only relevant for Dirichlet & FuzzyK that emit all points subject to the threshold above.

I'm not convinced removing EmitMostLikely makes sense but am not hung up and would like to hear more discussion from our user base.
