Constructor Detail

MetaCostModel

public MetaCostModel(ExampleSet exampleSet,
                     Model[] models,
                     double[][] costMatrix)

Method Detail

getNumberOfModels

public int getNumberOfModels()

getModel

public Model getModel(int index)

Returns a binary decision model for the given classification index.

getCostValue

public double getCostValue(int i,
                           int j)

Returns a single value from the cost matrix.

performPrediction

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

Description copied from class: PredictionModel

Subclasses should iterate through the given example set and set the prediction for each example. The given predicted label attribute was already be added to the example set and should be used to set the predicted values.

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:
