Constructor Detail

MultiModel

public MultiModel(ExampleSet exampleSet,
                  Model[] models)

Method Detail

getNumberOfModels

public int getNumberOfModels()

getModel

public Model getModel(int index)

Returns a binary decision model for the given classification index.

performPrediction

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

Iterates over all classes of the label and applies one model for each class. For each example the predicted label is determined by choosing the model with the highest confidence.

Specified by:

performPrediction in class PredictionModel

Throws:

OperatorException

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
