Method Detail

checkCompatibility

protected void checkCompatibility(ExampleSet exampleSet)
                           throws OperatorException

Description copied from class: AbstractPerformanceEvaluator

Performs a check if this operator can be used for this type of exampel set at all.

Specified by:

checkCompatibility in class AbstractPerformanceEvaluator

Throws:

OperatorException

getClassWeights

protected double[] getClassWeights(Attribute label)
                            throws UndefinedParameterError

Description copied from class: AbstractPerformanceEvaluator

Delivers class weights for performance criteria which implement the ClassWeightedPerformance interface. Might return null (for example for regression task performance evaluators).

Specified by:

getClassWeights in class AbstractPerformanceEvaluator

Throws:

UndefinedParameterError

getCriteria

public java.util.List<PerformanceCriterion> getCriteria()

Description copied from class: AbstractPerformanceEvaluator

Delivers the list of criteria which is able for this operator. Please note that all criteria in the list must be freshly instantiated since no copy is created in different runs of this operator. This is important in order to not mess up the results. This method must not return null but should return an empty list in this case.

Specified by:

getCriteria in class AbstractPerformanceEvaluator

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 AbstractPerformanceEvaluator
