Class BinDiscretization

java.lang.Object
  com.rapidminer.operator.Operator
      com.rapidminer.operator.preprocessing.PreprocessingOperator
          com.rapidminer.operator.preprocessing.discretization.BinDiscretization

All Implemented Interfaces:

ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class BinDiscretization
extends PreprocessingOperator

This operator discretizes all numeric attributes in the dataset into nominal attributes. This discretization is performed by simple binning, i.e. the specified number of equally sized bins is created and the numerical values are simply sorted into those bins. Skips all special attributes including the label.

Method Detail

createPreprocessingModel

public Model createPreprocessingModel(ExampleSet exampleSet)
                               throws OperatorException

Specified by:

createPreprocessingModel in class PreprocessingOperator

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.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class PreprocessingOperator
