Class SVMWeighting

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

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

public class SVMWeighting
extends AbstractWeighting
extends AbstractWeighting

Uses the coefficients of the normal vector of a linear SVM as feature weights. In contrast to most of the SVM based operators available in RapidMiner, this one works for multiple classes, too. Please note that the attribute values, however, still have to be numerical. Please use appropriate preprocessing operators in order to ensure this.

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.
