class mlpack::ann::MultiplyConstant< InputDataType, OutputDataType >

Implementation of the multiply constant layer.

The multiply constant layer multiplies the input by a (non-learnable) constant.

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).

Member Function Documentation

Backward()

void Backward	(	const DataType &	,
		const DataType &	gy,
		DataType &	g
	)

Ordinary feed backward pass of a neural network.

The backward pass multiplies the error with the specified constant scalar value.

Parameters

*	(input) The propagated input activation.
gy	The backpropagated error.
g	The calculated gradient.

Delta() [1/2]

OutputDataType& Delta ( ) const

inline

Get the delta.

Definition at line 81 of file multiply_constant.hpp.

Delta() [2/2]

OutputDataType& Delta ( )

inline

Modify the delta.

Definition at line 83 of file multiply_constant.hpp.

Forward()

void Forward	(	const InputType &	input,
		OutputType &	output
	)

Ordinary feed forward pass of a neural network.

Multiply the input with the specified constant scalar value.

Parameters

input	Input data used for evaluating the specified function.
output	Resulting output activation.

operator=() [1/2]

MultiplyConstant& operator=

(

const MultiplyConstant< InputDataType, OutputDataType > &

layer

)

Copy assignment operator.

operator=() [2/2]

MultiplyConstant& operator=

(

MultiplyConstant< InputDataType, OutputDataType > &&

layer

)

Move assignment operator.

OutputParameter() [1/2]

OutputDataType& OutputParameter ( ) const

inline

Get the output parameter.

Definition at line 76 of file multiply_constant.hpp.

OutputParameter() [2/2]

OutputDataType& OutputParameter ( )

inline

Modify the output parameter.

Definition at line 78 of file multiply_constant.hpp.

Scalar() [1/2]

double Scalar ( ) const

inline

Get the scalar multiplier.

Definition at line 86 of file multiply_constant.hpp.

Scalar() [2/2]

double& Scalar ( )

inline

Modify the scalar multiplier.

Definition at line 88 of file multiply_constant.hpp.

serialize()

void serialize	(	Archive &	ar,
		const uint32_t
	)

Serialize the layer.
