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


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
