public class Neuron
extends Node

Neuron is one of the nodes in a Brain. Neurons have a type, a bias, a sum, and a modulation.

There are several types of neuron. When the activation function is triggered,

• Workers transmit a "normal" signal.
• Exciters change modulation in postsynaptic neurons, increasing firing probability.
• Suppressors change modulation in postsynaptic neurons, decreasing firing probability.

Neurons are connected to other neurons by Synapses. Neurons fire signals along synapses when bias + modulation + sum triggers the activation function (currently ReLU, aka >0).

The "from" end of a synapse is also known as the pre synaptic neuron. the "to" end is the post synaptic neuron.

Method Details

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.

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.

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.

getBias

public double getBias()

setBias

public void setBias(double bias)

getSum

public double getSum()

setSum

public void setSum(double sum)

getNeuronType

public Neuron.Type getNeuronType()

setNeuronType

public void setNeuronType(Neuron.Type neuronType)

getModulation

public double getModulation()

setModulation

public void setModulation(double modulation)

activationFunction

public boolean activationFunction()

ReLU activation function

Returns:

true if the neuron should fire.
