TanHOutputFunction

public TanHOutputFunction()

Method Detail

computeDerivativeAtPos

public Type computeDerivativeAtPos(Type pos)

Specified by:

computeDerivativeAtPos in interface NeuronFunction

computeDerivativeUsingLastOutput

public Type computeDerivativeUsingLastOutput(Type lastOut)

Specified by:

computeDerivativeUsingLastOutput in interface NeuronFunction

computeFunction

public Type computeFunction(Type in)

Specified by:

computeFunction in interface NeuronFunction

getClone

public TanHOutputFunction getClone()

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface NeuronFunction

Specified by:

getClone in interface Cloneable

Returns:

An exact clone of the current object instance.

Object.clone()

getLowerActiveRange

public double getLowerActiveRange()

Return the lowerbound for the active range of this NeuronFunction The active range is -Sqrt(3) - Sqrt(3), and Sqrt(3) = 1.732050808

Specified by:

getLowerActiveRange in interface NeuronFunction

Returns:

the lowerbound

getUpperActiveRange

public double getUpperActiveRange()

Return the upperbound for the active range of this NeuronFunction

Specified by:

getUpperActiveRange in interface NeuronFunction

Returns:

the upperbound
