Method Detail

getUniqueName

public java.lang.String getUniqueName()

Description copied from class: AbstractRepresentation

Returns a unique name of this representation calculated by its parameters/structure. This is mostly used for identification.

Specified by:

getUniqueName in class AbstractRepresentation

Returns:

a unique name of this representation instance.

getNumberofMutationFunctions

public int getNumberofMutationFunctions()

Description copied from class: AbstractRepresentation

Returns the number of implemented mutation functions.

Specified by:

getNumberofMutationFunctions in class AbstractRepresentation

Returns:

the number of mutation functions implemented by this class.

getNumberOfRecombinationFunctions

public int getNumberOfRecombinationFunctions()

Description copied from class: AbstractRepresentation

Returns the number of implemented crossover functions.

Specified by:

getNumberOfRecombinationFunctions in class AbstractRepresentation

Returns:

the number of recombination functions implemented by this class.

mutateBias

public void mutateBias(float severity,
              float p,
              int method)

mutateWeight

public void mutateWeight(float severity,
                float p,
                int method)

recombinationFunction

public void recombinationFunction(AbstractRepresentation other,
                         int method)

Description copied from class: AbstractRepresentation

Specific implementation of the recombination function that initiates a crossover on this representation and with the given representation with the provided function.
Use AbstractRepresentation.getNumberOfRecombinationFunctions() to obtain the number of implemented recombination functions.

activate

public float activate(float x)

reset

public void reset()

Description copied from class: AbstractRepresentation

Resets the representation to its base state. Typically this is meant to erases cache for representations possessing some memory.

Specified by:

reset in class AbstractRepresentation

getOutput

public java.util.ArrayList<java.lang.Float> getOutput(java.util.ArrayList<java.lang.Float> input)

Provides the networks output for the given input

Specified by:

getOutput in class AbstractRepresentation

Parameters:

input - The list of input values to be processed.

Returns:

a list of output values.

getStep

public java.util.ArrayList<java.lang.Float> getStep(java.util.ArrayList<java.lang.Float> input)

diffTo

public double diffTo(AbstractRepresentation o)

Description copied from class: AbstractRepresentation

Compares this representation to another one. Basically, this function should provide a value measuring the distance from another representation of the same type.

Specified by:

diffTo in class AbstractRepresentation

Parameters:

o - The other representation to compare to.

Returns:

a value representing the distance between the two candidates.

cloneFunction

public AbstractRepresentation cloneFunction()

Description copied from class: AbstractRepresentation

Creates a full clone of this representation. The returned object must be a deep copy of this representation.

Returns:

a deep copy of this representation.

getWeight

public float getWeight(int nr,
              int from)

exportToXmlElement

public org.dom4j.Element exportToXmlElement(org.dom4j.Element element)

Method used for saving the properties of this component

Specified by:

exportToXmlElement in class AbstractRepresentation

Parameters:

element - The root element to be used for saving.

loadFromXML

public AbstractRepresentation loadFromXML(org.dom4j.Node nd)

Description copied from class: AbstractRepresentation

Reconstructs this representation from the given XML node.

Specified by:

loadFromXML in class AbstractRepresentation

Parameters:

nd - The root XML node to load the data from.

Returns:

a newly created representation built from the provided data.

getDetails

public java.util.Hashtable<java.lang.String,java.lang.String> getDetails()

Description copied from class: AbstractRepresentation

Returns a table of key-value pairs that describes this representation. This data is mostly used to visualize this specific representation instance.

Specified by:

getDetails in class AbstractRepresentation

Returns:

a human-readable table about the details/configuration of this specific instance

exportToFile

public void exportToFile(java.io.File saveFile)

Description copied from class: AbstractRepresentation

Exports the content of this representation to a file. Format and type is custom defined.

Specified by:

exportToFile in class AbstractRepresentation

Parameters:

saveFile - The file to be saved to
