Detailed Description

template<typename InputDataType, typename OutputDataType, typename RegularizerType>
class mlpack::ann::LinearNoBias< InputDataType, OutputDataType, RegularizerType >

Implementation of the LinearNoBias class.

The LinearNoBias class represents a single layer of a neural network.

Template Parameters

InputDataType	Type of the input data (arma::colvec, arma::mat, arma::sp_mat or arma::cube).
OutputDataType	Type of the output data (arma::colvec, arma::mat, arma::sp_mat or arma::cube).

Definition at line 96 of file layer_types.hpp.
