## Constructor & Destructor Documentation

### mlpack::amf::SVDIncompleteIncrementalLearning::SVDIncompleteIncrementalLearning (doubleu = `0.001`, doublekw = `0`, doublekh = `0`)` [inline]`

Definition at line 11 of file svd\_incomplete\_incremental\_learning.hpp.

## Member Function Documentation

### template\<typename MatType \> void mlpack::amf::SVDIncompleteIncrementalLearning::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:**

*V* Input matrix to be factorized. \
 *W* Basis matrix. \
 *H* Encoding matrix to be updated.

Definition at line 81 of file svd\_incomplete\_incremental\_learning.hpp.

### template\<typename MatType \> void mlpack::amf::SVDIncompleteIncrementalLearning::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:**

*V* Input matrix to be factorized. \
 *W* Basis matrix to be updated. \
 *H* Encoding matrix.
