Public Methods

Method Description
CreateLibraryCppn ( ) : IActivationFunctionLibrary

Create an IActivationFunctionLibrary for use with CPPNs.
CreateLibraryNeat ( IActivationFunction activationFn ) : IActivationFunctionLibrary

Create an IActivationFunctionLibrary for use with NEAT. NEAT uses the same activation function for all neurons/nodes therefore this factory method creates an IActivationFunction containing only the single provided IActivationFunction.
CreateLibraryRbf ( IActivationFunction activationFn, double auxArgsMutationSigmaCenter, double auxArgsMutationSigmaRadius ) : IActivationFunctionLibrary

Create an IActivationFunctionLibrary for use with Radial Basis Function NEAT.
DefaultActivationFunctionLibrary ( IList fnList ) : System.Collections.Generic

Constructs an activation function library with the provided list of activation functions.
GetFunction ( int id ) : IActivationFunction

Gets the function with the specified integer ID.
GetFunctionList ( ) : IList

Gets a list of all functions in the library.
GetRandomFunction ( XorShiftRandom rng ) : ActivationFunctionInfo

Randomly select a function based on each function's selection probability.
