Constructor Detail

AdaBoostModel

public AdaBoostModel(ExampleSet exampleSet,
                     java.util.List<Model> models,
                     java.util.List<java.lang.Double> weights)

Method Detail

setParameter

public void setParameter(java.lang.String name,
                         java.lang.String value)
                  throws OperatorException

Setting the parameter MAX_MODEL_NUMBER allows to discard all but the first n models for specified n.

Throws:

OperatorException

setMaxModelNumber

public void setMaxModelNumber(int numModels)

Using this setter with a positive value makes the model discard all but the specified number of base models. A value of -1 turns off this option.

getVisualizationComponent

public java.awt.Component getVisualizationComponent(IOContainer container)

Description copied from class: ResultObjectAdapter

Returns a editor pane that displays the ResultObjectAdapter.toResultString() result encoded as html. Please note that the returned pane is already enclosed by a scroll pane. If you overwrite this method you should again ensure that the returned component is scrollable. The given container is totally ignored.

Specified by:

getVisualizationComponent in interface ResultObject

Overrides:

getVisualizationComponent in class ResultObjectAdapter

toString

public java.lang.String toString()

Specified by:

toString in interface Readable

Overrides:

toString in class PredictionModel

Returns:

a String representation of this boosting model.

getNumberOfModels

public int getNumberOfModels()

Returns:

the number of embedded models

getModel

public Model getModel(int index)

Getter method for embedded models

Parameters:

index - the number of a model part of this boost model

Returns:

binary or nominal decision model

performPrediction

public ExampleSet performPrediction(ExampleSet origExampleSet,
                                    Attribute predictedLabel)
                             throws OperatorException

Iterates over all models and returns the class with maximum likelihood.

Specified by:

performPrediction in class PredictionModel

Parameters:

origExampleSet - the set of examples to be classified

Throws:

OperatorException
