Class GenericTopologyBuilder

java.lang.Object
  net.sourceforge.cilib.neuralnetwork.generic.topologybuilders.GenericTopologyBuilder

All Implemented Interfaces:

Initializable

Direct Known Subclasses:

FFNNgenericTopologyBuilder

public abstract class GenericTopologyBuilder
extends Object
implements Initializable

Author:

stefanv This class froms the base for building any NN topology. It provides a few basic tools such as contructing a layered topology, either connected or not connected. This provides a base for createLayerList(). createLayerList() and createNeuronPipePool() are implemented in sub classes and together are responsible for building a valid topology (Builder Design Pattern).
