Subject [jira] [Commented] (MAHOUT-1080) Kmeans clustered output losses vectorId given in the input
Date Sat, 01 Jun 2013 17:55:22 GMT

    [ https://issues.apache.org/jira/browse/MAHOUT-1080?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13672182#comment-13672182

Grant Ingersoll commented on MAHOUT-1080:
-----------------------------------------

Here's a thought: kill NamedVector, and move the single "name" string to Vector.  It seems
to me naming a Vector is very, very common.  A possible issue, however, is dealing with older
Vectors that don't have a name, but we could just treat it as an empty string.

IMO, this should be fixed before 1.0
