C# Class SharpNeat.Network.RbfGaussian

Gaussian activation function. Output range is 0 to 1, that is, the tails of the gaussian distribution curve tend towards 0 as abs(x) -> Infinity and the gaussian's peak is at x = 0.

Méthode Description
Calculate ( double x, double auxArgs ) : double

Calculates the output value for the specified input value and activation function auxiliary arguments.
Calculate ( float x, float auxArgs ) : float

Calculates the output value for the specified input value and activation function auxiliary arguments. This single precision overload of Calculate() will be used in neural network code that has been specifically written to use floats instead of doubles.
GetRandomAuxArgs ( XorShiftRandom rng, double connectionWeightRange ) : double[]

For activation functions that accept auxiliary arguments; generates random initial values for aux arguments for newly added nodes (from an 'add neuron' mutation).
MutateAuxArgs ( double auxArgs, XorShiftRandom rng, SharpNeat.Utility.ZigguratGaussianSampler gaussianSampler, double connectionWeightRange ) : void

Genetic mutation for auxiliary argument data.
RbfGaussian ( double auxArgsMutationSigmaCenter, double auxArgsMutationSigmaRadius ) : System

Construct with the specified radial basis function auxiliary arguments.
