Data Structures

class  nmf_config
 Configuration class for the nonnegative-matrix-factorization algorithm. Specify tolerances, maximum iteration counts, etc., here. More...

Namespaces

namespace  viennacl
 

Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.


namespace  viennacl::linalg
 

Provides all linear algebra operations which are not covered by operator overloads.


Functions

template<typename ScalarType >
void nmf (viennacl::matrix< ScalarType > const &V, viennacl::matrix< ScalarType > &W, viennacl::matrix< ScalarType > &H, nmf_config const &conf)
 The nonnegative matrix factorization (approximation) algorithm as suggested by Lee and Seung. Factorizes a matrix V with nonnegative entries into matrices W and H such that ||V - W*H|| is minimized.

Detailed Description

Provides a nonnegative matrix factorization implementation. Experimental.
