All Implemented Interfaces:

GaugeSource

public class Hebbian
extends Synapse

Hebbian.

Field Summary

Fields inherited from class org.simnet.interfaces.Synapse

id, increment, lowerBound, NUM_PARAMETERS, source, spikeResponder, strength, target, upperBound

Constructor Summary

Hebbian()
Default constructor needed for external calls which create neurons then set their parameters.

Hebbian(Neuron source, Neuron target)
Creates a weight connecting source and target neurons.

Hebbian(Neuron src, Neuron tar, double val, String theId)
Creates a weight of some value connecting two neurons.

Hebbian(Synapse s)
This constructor is used when creating a neuron of one type from another neuron of another type Only values common to different types of neuron are copied.
