Lance Norskog updated MAHOUT-838:
---------------------------------
Attachment: MAHOUT-838.patch
Above comments are implemented.
The ConfusionMatrix default column thing is clumsy. This printing code decides
that if there are no unclassified items, then the user did not intend to have
unclassified items.
The MatrixDumper does row & column headers from the matrix now.
> Make the confusion matrix writable to a file when testing classifiers

> fit in terminal window. Would be nice if we could write it out to a file.
