Subject [jira] [Updated] (MAHOUT-838) Make the confusion matrix writable to a file when testing classifiers
Date Mon, 31 Oct 2011 06:32:32 GMT

     [ https://issues.apache.org/jira/browse/MAHOUT-838?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.

> If you have a lot of labels for a classifier, the confusion matrix is hard to fit in
terminal window.  Would be nice if we could write it out to a file.
