Antoine Liutkus let me know of the beta_ntf package in Python so that I would include it on the Matrix Factorization Jungle page. From the super beta_ntf 2000 page:
In a nutshell, the beta_ntf module
- supports weighted parafac factorization of nonnegative numpy ndarray of arbitrary shape minimizing any β-divergence
- fits in one small single .py file
- requires numpy v1.6
You can check more details and download it here : http://code.google.com/p/beta-ntf/
If you, like Antoine think that a package needs to be added to the Advanced Matrix Factorization Jungle page, please do let me know, I'll be glad to add it.
