keel.Algorithms.Preprocess.Transformations.Nominal2Binary.Nominal2Binary

public class Nominal2Binary
extends java.lang.Object

This class performs the nominal to binary transformation. A nominal attribute is broken down into several binary ones, one per nominal value of the original attribute. These new attributes will present the '1' value if the nominal value was present, '0' otherwise.

public void transform()

Process the training and test files provided in the parameters file to the constructor.

convertNominal2Binary

public InstanceSet convertNominal2Binary(InstanceSet is)

Creates a new allocated KEEL's set of Instances (i.e. Instances) from a KEEL's set of instances (i.e. InstanceSet). The new InstanceSet will not contain nominal values, as they have been transformed into binary attributes.

Parameters:

is - The original KEEL Instance set

Returns:

A new allocated KEEL formatted Instance set
