Subject [jira] [Updated] (MAHOUT-524) DisplaySpectralKMeans example fails
Date Tue, 24 May 2011 09:20:47 GMT


Sean Owen updated MAHOUT-524:

    Affects Version/s: 0.5
        Fix Version/s: 0.6
             Assignee: Jeff Eastman
               Labels: clustering k-means visualization  (was: )

It seems like there's an issue here that should be fixed with some priority.

> I've committed a new display example that attempts to push the standard mixture of models
data set through spectral k-means. After some tweaking of configuration arguments and a bug
fix in EigenCleanupJob it runs spectral k-means to completion. The display example is expecting
2-d clustered points and the example is producing 5-d points. Additional I/O work is needed
before this will play with the rest of the clustering algorithms.
