C# Class AForge.Neuro.ThresholdFunction

Threshold activation function.

The class represents threshold activation function with the next expression: f(x) = 1, if x >= 0, otherwise 0

Output range of the function: [0, 1].

Public Methods

Method	Description
Clone ( ) : object	Creates a new object that is a copy of the current instance.
Derivative ( double x ) : double	Calculates function derivative (not supported). The method is not supported, because it is not possible to calculate derivative of the function.
Derivative2 ( double y ) : double	Calculates function derivative (not supported). The method is not supported, because it is not possible to calculate derivative of the function.
Function ( double x ) : double	Calculates function value. The method calculates function value at point x.
ThresholdFunction ( ) : System	Initializes a new instance of the ThresholdFunction class.

Creates a new object that is a copy of the current instance.

public Clone ( ) : object
return	object

Calculates function derivative (not supported).

The method is not supported, because it is not possible to calculate derivative of the function.

public Derivative ( double x ) : double
x	double	Input value.
return	double

Calculates function derivative (not supported).

The method is not supported, because it is not possible to calculate derivative of the function.

public Derivative2 ( double y ) : double
y	double	Input value.
return	double

Calculates function value.

The method calculates function value at point x.

public Function ( double x ) : double
x	double	Function input value.
return	double

Initializes a new instance of the ThresholdFunction class.
