com.rapidminer.operator.features.weighting
Class SymmetricalUncertaintyOperator

java.lang.Object
  com.rapidminer.operator.Operator
      com.rapidminer.operator.features.weighting.AbstractWeighting
          com.rapidminer.operator.features.weighting.SymmetricalUncertaintyOperator

All Implemented Interfaces:: ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class SymmetricalUncertaintyOperator
extends AbstractWeighting
extends AbstractWeighting

This operator calculates the relevance of an attribute by measuring the symmetrical uncertainty with respect to the class. The formulaization for this is:

relevance = 2 * (P(Class) - P(Class | Attribute)) / P(Class) + P(Attribute)

calculateWeights

public AttributeWeights calculateWeights(ExampleSet exampleSet)
                                  throws OperatorException

Specified by:: calculateWeights in class AbstractWeighting

Throws:: OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.
