Hi community,
I'm dealing with a problem which needs NMF(Non-negative Matrix
I've looked up the document along with Mathematica, but nothing found.
And I've tried to implement one function, however, the efficiency is too
poor in comparison with built-in SingularValueDecompostion[].
Is there any implement of NMF?

Thank you all!
