class mlpack::ann::Linear3D< InputDataType, OutputDataType, RegularizerType >

Implementation of the Linear3D layer class.

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

Shape of input : (inSize * nPoints, batchSize) Shape of output : (outSize * nPoints, batchSize)

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 114 of file layer_types.hpp.
