Method Detail

getIdentifier

public java.lang.String getIdentifier()

Returns:

the static class identifier of this model

performPrediction

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

Description copied from class: PredictionModel

Subclasses should iterated 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

                             throws java.io.IOException

Description copied from class: PredictionModel

Reads the model data (without label).

Specified by:

readPredictionModelData in class PredictionModel

Throws:

java.io.IOException

writePredictionModelData

public void writePredictionModelData(java.io.ObjectOutputStream out)
                              throws java.io.IOException

Description copied from class: PredictionModel

Writes the model data (without label).

Specified by:

writePredictionModelData in class PredictionModel

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class PredictionModel

Returns:

a String representation of this scaling model.
