Syntax

struct FNeuralNetworkCritic

Remarks

Neural-network based critic object. Stores various settings and intermediate storage required to evaluate the given network for the provided number of instances.

Constructors

  Type Name Description
Public function  

FNeuralNetworkCritic ( const int32 InMaxInstanceNum,
const int32 InObservationEncodedNum,
const int32 InMemoryStateNum,
const TSharedPtr< FNeuralNetwork >& InNeuralNetwork,
const FNeuralNetworkInferenceSettings& InInferenceSettings
)

 Create a new Critic Object which takes the encoded observation state, and the memory state, and outputs the expected discounted returns.
