Method Details

update

public void update(double dt)

Description copied from class: Node

Called every frame.

Overrides:

update in class Node

Parameters:

dt - the time since the last frame.

getIcon

public Icon getIcon()

Description copied from class: Node

Set a custom icon for this node.

Overrides:

getIcon in class Node

Returns:

the icon, or null if none.

scan

public void scan()

Scan all children of this brain to collect all neurons and synapses. Updates the bounding box of the brain, as well as the neurons and synapses lists

isEmpty

public boolean isEmpty()

getNeurons

public List<Neuron> getNeurons()

getSynapses

public List<Synapse> getSynapses()

getComponents

public void getComponents(List<JPanel> list)

Description copied from class: Node

Build a Swing Component that represents this Node.

Overrides:

getComponents in class Node

Parameters:

list - the list to add components to.

toJSON

public org.json.JSONObject toJSON()

Description copied from class: Node

Serialize this node and its children to a JSON object and its children. Classes that override this method should call super.toJSON() first, then add to the object returned.

Overrides:

toJSON in class Node

Returns:

the JSON object.

fromJSON

public void fromJSON(org.json.JSONObject json)

Description copied from class: Node

Deserialize this node and its children from a JSON object and its children. Classes that override this method should call super.fromJSON(). When they do it will trigger the creation of child nodes. The child nodes will then call their own fromJSON() methods.

Overrides:

fromJSON in class Node

Parameters:

json - the JSON object to read from.

setInputs

public void setInputs(int newCount)

setOutputs

public void setOutputs(int newCount)

setListSize

public void setListSize(ListWithEvents<NodePath<Neuron>> list,
 int newCount)

getOutput

public double getOutput(int i)

Get the sum of output neuron i.

Parameters:

i - the index of the neuron

Returns:

the sum of the neuron or zero if the neuron is not found.

Throws:

InvalidParameterException - if the index is out of range

setInput

public void setInput(int i,
 double v)

Set the sum of input neuron i.

Parameters:

i - the index of the neuron

v - the new sum

Throws:

InvalidParameterException - if the index is out of range

decaySums

public void decaySums()

getSumDecay

public double getSumDecay()

setSumDecay

public void setSumDecay(double v)

getLearningRate

public double getLearningRate()

setLearningRate

setModulationDegradationRate

public void setModulationDegradationRate(double v)

getModulationDegradationRate

public double getModulationDegradationRate()
