Definition at line 144 of file dueling_dqn.hpp.

◆ DuelingDQN() [4/4]

DuelingDQN ( const DuelingDQN< OutputLayerType, InitType, CompleteNetworkType, FeatureNetworkType, AdvantageNetworkType, ValueNetworkType > & )

inline

Copy constructor.

Definition at line 163 of file dueling_dqn.hpp.

Member Function Documentation

◆ Backward()

void Backward	(	const arma::mat	state,
		arma::mat &	target,
		arma::mat &	gradient
	)

inline

Perform the backward pass of the state in real batch mode.

Parameters

state	The input state.
target	The training target.
gradient	The gradient.

Definition at line 221 of file dueling_dqn.hpp.

◆ Forward()

void Forward	(	const arma::mat	state,
		arma::mat &	actionValue
	)

inline

Perform the forward pass of the states in real batch mode.

Parameters

state	The input state.
actionValue	Matrix to put output action values of states input.

Definition at line 203 of file dueling_dqn.hpp.

◆ operator=()

void operator= ( const DuelingDQN< OutputLayerType, InitType, CompleteNetworkType, FeatureNetworkType, AdvantageNetworkType, ValueNetworkType > & model )

inline

Copy assignment operator.

Definition at line 167 of file dueling_dqn.hpp.

◆ Parameters() [1/2]

arma::mat& Parameters ( )

inline

Modify the Parameters.

Definition at line 258 of file dueling_dqn.hpp.

◆ Parameters() [2/2]

const arma::mat& Parameters ( ) const

inline

Return the Parameters.

Definition at line 256 of file dueling_dqn.hpp.

◆ Predict()

void Predict	(	const arma::mat	state,
		arma::mat &	actionValue
	)

inline

Predict the responses to a given set of predictors.

The responses will reflect the output of the given output layer as returned by the output layer function.

If you want to pass in a parameter and discard the original parameter object, be sure to use std::move to avoid unnecessary copy.

Parameters

state	Input state.
actionValue	Matrix to put output action values of states input.

Definition at line 187 of file dueling_dqn.hpp.

◆ ResetNoise()

void ResetNoise ( )

inline

Resets noise of the network, if the network is of type noisy.

Definition at line 244 of file dueling_dqn.hpp.

◆ ResetParameters()

void ResetParameters ( )

inline

Resets the parameters of the network.

Definition at line 236 of file dueling_dqn.hpp.
