Interface Summary

Interface	Description
Function.Spline	Spline function interface.

Class Summary

Class	Description
Function	A function that generates an output value from input values.
Function.AboutEqual	About Equal: return 1.0 if (eqValue - range) < value < (eqValue + range).
Function.AtLeast	At Least: return 1.0 if value >= minValue, 0.0 else.
Function.AtMost	At Most: return 1.0 if value <= maxValue, 0.0 else.
Function.CatmullRomSpline	Catmull-Rom Spline Activation Function.
Function.Clip	Clip: return value if value in the given range, else the low/high range border value.
Function.Composition	composition function, returns g(f(x)).
Function.Exponential	The plain exponential function f(x) = e^x with caching.
Function.GreaterThan	Greater Than (strict): return 1.0 if value > minValue, 0.0 else.
Function.Identity	identity function - maps input to output
Function.LessThan	Less Than (strict): return 1.0 if value < maxValue, 0.0 else.
Function.NaturalSpline	Natural Cubic Spline Activation Function
Function.ReLU	The rectified linear unit (ReLU) function f(x) = max(0, x) with first derivative.
Function.Scaled	function adding scaling factors, applied to the function result value (outside).
Function.Sigmoid	The sigmoid function f(x) = 1 / (1 + e^(-x)) with first and second derivative.
Function.Signum	Signum: 1 if > 0, -1 if < 0, 0 if = 0
Function.SignumWithoutZero	Signum Without Zero: 1 if > 0, -1 else
Function.Sinus	Sinus: sin(factor * x) Default: factor = 0.1 First and Second Derivatives are implemented.
Function.SoftMax	The softmax function mapping an array of values to a probability distribution by f(xi) = e^(xi) / sumi(e^(xi)).
Function.TanH	The tanh function f(x) = (e^x - e^-x) / (e^x + e^-x) with caching and fast, numerically safe computation.
HexagonTopology	A hexagonal output map.
Position	A 3D neuron position description.
Topology	The topology defines the neighborhood relation of the output neurons so as to form a map of neurons.

Exception Summary

Exception	Description
Function.NotImplemented	Runtime exception to throw for something that is not implemented.
