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
