Constructor & Destructor Documentation

SimpleDQN() [1/2]

template<typename OutputLayerType = MeanSquaredError<>, typename InitType = GaussianInitialization, typename NetworkType = FFN<OutputLayerType, InitType>>

mlpack::rl::SimpleDQN< OutputLayerType, InitType, NetworkType >::SimpleDQN ( const int  inputDim, const int  h1, const int  h2, const int  outputDim, const bool  isNoisy = false, InitType  init = InitType(), OutputLayerType  outputLayer = OutputLayerType()  )

inline

Construct an instance of SimpleDQN class.

Parameters

inputDim	Number of inputs.
h1	Number of neurons in hiddenlayer-1.
h2	Number of neurons in hiddenlayer-2.
outputDim	Number of neurons in output layer.
isNoisy	Specifies whether the network needs to be of type noisy.
init	Specifies the initialization rule for the network.
outputLayer	Specifies the output layer type for network.

SimpleDQN() [2/2]

template<typename OutputLayerType = MeanSquaredError<>, typename InitType = GaussianInitialization, typename NetworkType = FFN<OutputLayerType, InitType>>

mlpack::rl::SimpleDQN< OutputLayerType, InitType, NetworkType >::SimpleDQN ( NetworkType &  network, const bool  isNoisy = false  )

inline

Construct an instance of SimpleDQN class from a pre-constructed network.

Parameters

network	The network to be used by SimpleDQN class.
isNoisy	Specifies whether the network needs to be of type noisy.

Member Function Documentation

Backward()

template<typename OutputLayerType = MeanSquaredError<>, typename InitType = GaussianInitialization, typename NetworkType = FFN<OutputLayerType, InitType>>

void mlpack::rl::SimpleDQN< OutputLayerType, InitType, NetworkType >::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.

Forward()

template<typename OutputLayerType = MeanSquaredError<>, typename InitType = GaussianInitialization, typename NetworkType = FFN<OutputLayerType, InitType>>

void mlpack::rl::SimpleDQN< OutputLayerType, InitType, NetworkType >::Forward ( const arma::mat  state, arma::mat &  target  )

inline

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

Parameters

state	The input state.
target	The predicted target.

Predict()

template<typename OutputLayerType = MeanSquaredError<>, typename InitType = GaussianInitialization, typename NetworkType = FFN<OutputLayerType, InitType>>

void mlpack::rl::SimpleDQN< OutputLayerType, InitType, NetworkType >::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.
