public class AverageModel
extends PredictionModel

Average model simply calculates the average of the attributes as prediction. For classification problems the class value closest to the prediction is returned.

Method Detail

writePredictionModelData

public void writePredictionModelData(java.io.ObjectOutputStream out)

Description copied from class: PredictionModel

Writes the model data (without label).

Specified by:

writePredictionModelData in class PredictionModel

readPredictionModelData

public void readPredictionModelData(java.io.ObjectInputStream in)

Description copied from class: PredictionModel

Reads the model data (without label).

Specified by:

readPredictionModelData in class PredictionModel

performPrediction

public void performPrediction(ExampleSet exampleSet,
                              Attribute predictedLabelAttribute)

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
