Detailed Description

template<typename InputDataType, typename OutputDataType, typename... CustomLayers>
class mlpack::ann::Sequential< InputDataType, OutputDataType, CustomLayers >

Implementation of the Sequential class.

The sequential class works as a feed-forward fully connected network container which plugs various layers together.

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 70 of file layer_types.hpp.
