Class XMLNeuralDataSet

java.lang.Object
  org.encog.neural.data.xml.XMLNeuralDataSet

All Implemented Interfaces:

java.lang.Iterable<NeuralDataPair>, NeuralDataSet

public class XMLNeuralDataSet
extends java.lang.Object
implements NeuralDataSet

A data source that reads XML files. This class is not memory based, so very large XML files can be used, without problem. The XML data is assumed to look something like below. The names of the tags can be configured using the various properties on this object. 00 0 10 1 01 1 11 0
