I am looking for an implementation of the basic non-negative matrix factorization (NMF) algorithm in Mathematica 8. A good reference to this interesting factorization is: Lee, D.D. and Seung, H.S. (1999) Learning the parts of objects by non-negative matrix factorization. /Nature/, *401* (21 October), pp. 788-791. Any code available would be appreciated. Note, the matrices involved could be large (>100000 elements). --V
