Method Detail

doWork

public AttributeWeights doWork(Model model,
                               ExampleSet exampleSet)
                        throws OperatorException

Helper method for anonymous instantiations of this class.

Throws:

OperatorException

calculateWeights

protected AttributeWeights calculateWeights(ExampleSet exampleSet)
                                     throws OperatorException

Specified by:

calculateWeights in class AbstractWeighting

Throws:

OperatorException

isExampleSetMandatory

protected boolean isExampleSetMandatory()

Overrides:

isExampleSetMandatory in class AbstractWeighting

supportsCapability

public boolean supportsCapability(OperatorCapability capability)

Description copied from interface: CapabilityProvider

Checks for Learner capabilities. Should return true if the given capability is supported.

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 AbstractWeighting
