Class ImageMLDataSet

java.lang.Object

org.encog.ml.data.basic.BasicMLDataSet

org.encog.platformspecific.j2se.data.image.ImageMLDataSet

All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable<MLDataPair>, MLDataSet

public class ImageMLDataSet
extends BasicMLDataSet

Store a collection of images for training with a neural network. This class collects and then downsamples images for use with a neural network. This is a memory based class, so large datasets can run out of memory.
