Subject [jira] [Commented] (MAHOUT-518) Implement Affinity Preprocessing for Eigencuts and Spectral KMeans
Date Sun, 03 Apr 2011 21:39:05 GMT

    [ https://issues.apache.org/jira/browse/MAHOUT-518?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13015231#comment-13015231

Shannon Quinn commented on MAHOUT-518:
--------------------------------------

I could make a patch that processes a basic CSV file of m n-dimensional points, but I still
wouldn't consider this issue closed, as the discussion regarding standardizing the input/output
formats for Mahout still seems to be ongoing, and isn't something that will be resolved for
0.5. Once it is resolved, this will likely still have to be modified, so a future version
would probably be best.

> The input format for these clustering algorithms is currently affinity tuples. It would
be very nice to have this process automated. Marking for 0.5 as this will require some investigation.
