Detailed Description

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

Implementation of the MultiplyMerge module class.

The MultiplyMerge class multiplies the output of various modules element-wise.

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).
CustomLayers	Additional custom layers that can be added.

Definition at line 202 of file layer_types.hpp.

Constructor & Destructor Documentation

MultiplyMerge	(	const bool	model = false,
		const bool	run = true
	)

Create the MultiplyMerge object using the specified parameters.

Parameters

model	Expose all the network modules.
run	Call the Forward/Backward method before the output is merged.

~MultiplyMerge

(

)

Destructor to release allocated memory.
