Class GenericWekaAttributeWeighting

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

All Implemented Interfaces:

ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler, weka.core.TechnicalInformationHandler

public class GenericWekaAttributeWeighting
extends AbstractWeighting
implements weka.core.TechnicalInformationHandler

Performs the AttributeEvaluator of Weka with the same name to determine a sort of attribute relevance. These relevance values build an instance of AttributeWeights. Therefore, they can be used by other operators which make use of such weights, like weight based selection or search heuristics which use attribute weights to speed up the search. See the Weka javadoc for further operator and parameter descriptions.

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.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class AbstractWeighting
