Member Function Documentation
template<typename MatType > static void mlpack::amf::NMFMultiplicativeDivergenceUpdate::HUpdate (const MatType &V, const arma::mat &W, arma::mat &H) [inline], [static]
The update rule for the encoding matrix H. The formula used is The function takes in all the matrices and only changes the value of the H matrix.
Parameters:
V Input matrix to be factorized.
W Basis matrix.
H Encoding matrix to updated.
