Member Function Documentation¶

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

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: Definition at line 101 of file svd_batch_learning.hpp. References kh, mH, momentum, and u.

template<typename MatType > void mlpack::amf::SVDBatchLearning::Initialize (const MatType &dataset, const size_trank) [inline]¶

Definition at line 42 of file svd_batch_learning.hpp. References mH, and mW.

template<typename MatType > void mlpack::amf::SVDBatchLearning::WUpdate (const MatType &V, arma::mat &W, const arma::mat &H) [inline]¶

The update rule for the basis matrix W. The function takes in all the matrices and only changes the value of the W matrix. Parameters: Definition at line 61 of file svd_batch_learning.hpp. References kw, momentum, mW, and u.
