public class NominalToBinominalModel
extends PreprocessingModel

This model maps the values of all nominal values to binary attributes. For example, if a nominal attribute with name "costs" and possible nominal values "low", "moderate", and "high" is transformed, the result is a set of three binominal attributes "costs = low", "costs = moderate", and "costs = high". Only one of the values of each attribute is true for a specific example, the other values are false.
