public class MinMaxBinDiscretization
extends AbstractDiscretizationOperator

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. In contrast to the usual simple binning performed by the BinDiscretization, this operator bins the values into a predefined range (and not into the range defined by the minimum and maximum values taken from the data).

Method Detail

createPreprocessingModel

public PreprocessingModel createPreprocessingModel(ExampleSet exampleSet)
                                            throws OperatorException

Specified by:

createPreprocessingModel in class PreprocessingOperator

Throws:

OperatorException

getPreprocessingModelClass

public java.lang.Class<? extends PreprocessingModel> getPreprocessingModelClass()

Specified by:

getPreprocessingModelClass in class PreprocessingOperator

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. ATTENTION! This will create new parameterTypes. For calling already existing parameter types use getParameters().getParameterTypes();

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class PreprocessingOperator

getResourceConsumptionEstimator

public ResourceConsumptionEstimator getResourceConsumptionEstimator()

Description copied from class: Operator

Subclasses can override this method if they are able to estimate the consumed resources (CPU time and memory), based on their input. The default implementation returns null.

Specified by:

getResourceConsumptionEstimator in interface ResourceConsumer

Overrides:

getResourceConsumptionEstimator in class Operator
