Looking for R-code for non-negative matrix factorization in the presence of Gaussian or Poisson noise
Hi all,
Has any of you implemented code for non-negative matrix factorization to solve
Y=T P' +E; dim(Y)=n,p ; dim(T)=n,nc; dim (P)=(p,nc); dim(E)=n,p
where T and P must be non-negative and E either Gaussian or Poisson noise.
I'm looking for two variants:
1. Easy (I think), T is known (that is we just want to solve the general inverse problem)
2. Harder (?), T is unknown (under some
