Member Function Documentation

template<typename MatType > void mlpack::amf::SVDBatchLearning::HUpdate (const MatType &V, const arma::mat &W, arma::mat &H)\fC [inline]\fP

The update rule for the encoding matrix H. 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 be updated.
