First of all, thanks for scikit-learn!
I was wondering if handling uncertainties in NMF would be possible.
Indeed, in NMF we minimize a Frobenius norm ||X - WH||², so we may quite
easily minimize ||(X - WH) / U||², with U the matrix of uncertainty.
This would be really helpfull in many field (atmospheric chemistry ,
biology , etc).
Does such feature is planed to be implemented in scikit-learn?
