[jira] [Commented] (MAHOUT-1053) Use KMeans++ for cluster Initialization

    [ https://issues.apache.org/jira/browse/MAHOUT-1053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13432894#comment-13432894 ] 

Ted Dunning commented on MAHOUT-1053:
-------------------------------------

I think that ball k-means and k-means++ are close enough as to be indistinguishable for practical purposes.  We don't need both.
