[jira] [Commented] (MAHOUT-524) DisplaySpectralKMeans example fails

Rozemary Scarlat commented on MAHOUT-524:
-----------------------------------------

Hi! I am new to Mahout and I have been trying to use the K-means Spectral Clustering, but I ran into the problem described in the comments above: the Lancsoz solver tries to input the output of the VectorMatrixMultipliction as a "calculations/laplacian-166/tmp/data" file, instead of the "calculations/laplacian-166/part-m-00000".
I was wondering if currently there is a way to a run the Spectral Clustering.

> 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.
