Detailed Description

A data-dependent random dictionary initializer for SparseCoding.

This creates random dictionary atoms by adding three random observations from the data together, and then normalizing the atom.

Initialize()

static void mlpack::sparse_coding::DataDependentRandomInitializer::Initialize ( const arma::mat &  data, const size_t  atoms, arma::mat &  dictionary  )

inlinestatic

Initialize the dictionary by adding together three random observations from the data, and then normalizing the atom.

This implementation is simple enough to be included with the definition.

Parameters

data	Dataset to initialize the dictionary with.
atoms	Number of atoms in dictionary.
dictionary	Dictionary to initialize.
