      marf.util.BaseThread
          marf.Classification.NeuralNetwork.Layer

All Implemented Interfaces:

java.io.Serializable, java.lang.Runnable

public class Layer
extends BaseThread
implements java.io.Serializable

Represents a Neural Network Layer. Being itself a thread, encapsulates a group of Neuron thread comprising a neuron layer of the network. The actual threading is almost unimplemented yet, but the class itself is properly synchronized.
