Class SwitchingForwardSelection

java.lang.Object
  com.rapidminer.operator.features.IndividualOperator
      com.rapidminer.operator.features.selection.SwitchingForwardSelection

All Implemented Interfaces:

PopulationOperator

public class SwitchingForwardSelection
extends IndividualOperator

This PopulationOperator realises forward selection, i.e. creates a list of clones of each individual and switches on one attribute in each of the clones. In contrast to the normal forward selection this one actually selects attributes instead of completely adding them. Although this might use more memory for simple selection tasks this might be necessary in case of FeatureOperators which generate new attributes.

Description copied from class: IndividualOperator

Subclasses must implement this method providing a list of new individuals. individual will be removed from the population so it might be useful to return a list of size 1 containing only the modified individual. If the original individual should also be part of the new population it must also be added to the result list.
