Detailed Description

This initialization rule for AMF simply fills the W and H matrices with the matrices given to the constructor of this object.

Note that this object does not use std::move() during the Initialize() method, so it can be reused for multiple AMF objects, but will incur copies of the W and H matrices.

Member Function Documentation

◆ Initialize()

template<typename MatType >

void mlpack::amf::GivenInitialization::Initialize	(	const MatType &	V,
		const size_t	r,
		arma::mat &	W,
		arma::mat &	H
	)

inline

Fill W and H with given matrices.

Parameters

V	Input matrix.
r	Rank of decomposition.
W	W matrix, to be initialized to given matrix.
H	H matrix, to be initialized to given matrix.
