Class UnbalancedCrossover

java.lang.Object
  com.rapidminer.operator.features.construction.ExampleSetBasedSelectionCrossover
      com.rapidminer.operator.features.construction.UnbalancedCrossover

All Implemented Interfaces:

ExampleSetBasedPopulationOperator

public class UnbalancedCrossover
extends ExampleSetBasedSelectionCrossover

This PopulationOperator applies a crossover on two example sets. Crossover type can be ONE_POINT, UNIFORM, or SHUFFLE. In difference to SelectionCrossover the attribute vectors can have different lengths.
This crossover type should only be used for SINGLE_VALUEs, i.e. attributes without a block number (blocknumber can and should be assigned to value series attributes)!
