Subject NMF on Mahout?
Date Mon, 26 Apr 2010 18:04:12 GMT
Hi All,
I have two simple questions:
1. Is there a Non-negative Matrix Factorization algorithim for Mahout?  I
did not see one in the algorithms section of the Mahout Wiki.

I have a matrix that has 3,000,000 by 70,000 entries, however it is very
sparse.  It could be broken down to 60,000,000 non-zero data points.

2. Am I better off using R, than Mahout?

Thanks for your help,
Peter Harrington
