Activation_Functions Class Reference

Activation functions applied to neurons of the whole layer. Per-neuron activation function setting is not supported. More...

#include <Activation_Functions.h>

List of all members.

Classes
struct	Function
	Holds enumeration of all available functions. More...
struct	Pair
	Structure that holds pointers to function and its derivative for convenient use. More...
Public Types
typedef double(*	Function_Ptr )(double)
	function pointer type for activation function and its derivative.
Public Member Functions
	Activation_Functions ()
	Constructor.
const Pair *	operator[] (const Function::Type index) const
	Allows to get the activation function and its derivative (in the form of Pair*) by index.
Static Public Member Functions
static double	tanh (double x)
	Hyperbolic tangent.
static double	tanh_derivative (double tanh_value)
	Hyperbolic tangent first derivative. Please note that tanh_value = tanh(x)!
static double	pass_through (double x)
	y(x) = x.
static double	pass_through_derivative (double x)
	First derivative of ( y(x) = x ) which is always 0.
