All Implemented Interfaces:

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

public class CSVNeuralDataSet
extends BasicMLDataSet

An implementation of the NeuralDataSet interface designed to provide a CSV file to the neural network. This implementation uses the BasicNeuralData to hold the data being read. This class has no ability to write CSV files. The columns of the CSV file will specify both the input and ideal columns. Because this class loads the CSV file to memory, it is quite fast, once the data has been loaded.
