public class NumericToBinominal
extends NumericToNominal

Converts all numerical attributes to binary ones. If the value of an attribute is between the specified minimal and maximal value, it becomes false, otherwise true. If the value is missing, the new value will be missing. The default boundaries are both set to 0, thus only 0.0 is mapped to false and all other values are mapped to true.

Method Detail

setValue

protected void setValue(Example example,
                        Attribute newAttribute,
                        double value)
                 throws OperatorException

Specified by:

setValue in class NumericToNominal

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 Operator

getGeneratedAttributevalueType

protected int getGeneratedAttributevalueType()

Description copied from class: NumericToNominal

Returns Ontology.NOMINAL or one of its subtypes.

Specified by:

getGeneratedAttributevalueType in class NumericToNominal

makeAttribute

protected Attribute makeAttribute()

Overrides:

makeAttribute in class NumericToNominal
