Field Summary

static java.lang.String	PARAMETER_MAX The parameter name for "The maximum value after normalization"
static java.lang.String	PARAMETER_MIN The parameter name for "The minimum value after normalization"

Constructor Summary

RangeNormalizationMethod()

Method Summary

java.lang.String	getName() This just returns the name of the method.
AbstractNormalizationModel	getNormalizationModel(ExampleSet exampleSet, Operator operator) This method will be called to build the normalization model from the given ExampleSet.
java.util.List<ParameterType>	getParameterTypes(ParameterHandler handler) If this method needs additional parameter types, they can be returned here.

modifyAttributeMetaData

public java.util.Collection<AttributeMetaData> modifyAttributeMetaData(ExampleSetMetaData emd,
                                                                       AttributeMetaData amd,

                                                                throws UndefinedParameterError

Description copied from interface: NormalizationMethod

This modifies the meta data of the given attribute and returns a collection of all derived attributes. In normal cases this is simply one single attribute.

parameterHandler - TODO

Throws:

UndefinedParameterError

getNormalizationModel

public AbstractNormalizationModel getNormalizationModel(ExampleSet exampleSet,
                                                        Operator operator)
                                                 throws UserError

Description copied from interface: NormalizationMethod

This method will be called to build the normalization model from the given ExampleSet. It will be called directly after init() is called.

operator - TODO

Throws:

UserError

getName

public java.lang.String getName()

Description copied from interface: NormalizationMethod

This just returns the name of the method.

getParameterTypes

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

Description copied from interface: NormalizationMethod

If this method needs additional parameter types, they can be returned here.
