public abstract class AbstractBootstrapping
extends AbstractSamplingOperator

This operator constructs a bootstrapped sample from the given example set. That means that a sampling with replacement will be performed. The usual sample size is the number of original examples. This operator also offers the possibility to create the inverse example set, i.e. an example set containing all examples which are not part of the bootstrapped example set. This inverse example set might be used for a bootstrapped validation (together with an IteratingPerformanceAverage operator.

createMapping

public abstract int[] createMapping(ExampleSet exampleSet,
                                    int size,
                                    java.util.Random random)
                             throws OperatorException

Throws:

OperatorException

apply

public ExampleSet apply(ExampleSet exampleSet)
                 throws OperatorException

Description copied from class: AbstractExampleSetProcessing

Delegate for the apply method. In most cases, the returned example set will be the same as the example set or a modified clone.

Specified by:

apply in class AbstractExampleSetProcessing

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
