Class AttributeGenerator

java.lang.Object
  com.rapidminer.operator.features.construction.ExampleSetBasedIndividualOperator
      com.rapidminer.operator.features.construction.AttributeGenerator

All Implemented Interfaces:

ExampleSetBasedPopulationOperator

public class AttributeGenerator
extends ExampleSetBasedIndividualOperator

This PopulationOperator generates new attributes in an individual's example table. Given a generation probability pGenerate

and the maximal number of new attributes it generates on average pGenerate * numberOfNewAttributes new attributes using generators from the list generatorList
This operator can never handle value series but only single attributes.
