Class BipolarNeuron

java.lang.Object
  dlife.nn.BipolarNeuron

All Implemented Interfaces:

Neuron, Serializable

public class BipolarNeuron
extends Object
implements Neuron

Implementation of a bipolar transfer function for a Neuron. This neuron has the transfer function:

• If x < 0 then the output is -1
• If x == 0 then the output is 0
• If x > 0 then the output is 1
