public class JMySVMModel
extends AbstractMySVMModel

The implementation for the mySVM model (Java version) by Stefan Rueping. The ModelApplier can have an parameter "function_values" with the value "true". Then the predicted Label contains the function values of the SVM.

Method Detail

createSVM

public SVMInterface createSVM()

Description copied from class: AbstractMySVMModel

Creates a new SVM for prediction.

Specified by:

createSVM in class AbstractMySVMModel

setPrediction

public void setPrediction(Example example,
                          double prediction)

Description copied from class: AbstractMySVMModel

Sets the correct prediction to the example from the result value of the SVM.

Specified by:

setPrediction in class AbstractMySVMModel

createPredictedLabel

protected Attribute createPredictedLabel(ExampleSet exampleSet)

Description copied from class: PredictionModel

Creates a predicted label for the given example set based on the label attribute defined for this prediction model. Subclasses which override this method should first invoke super.createPredictedLabel(exampleSet) and should then replace the attribute with a new predicted label attribute via a method call like exampleSet.replaceAttribute(predictedLabel, AttributeFactory.changeValueType(predictedLabel, Ontology.REAL)); . This might be usefull in cases where a crisp nominal prediction should be replace by confidence predictions.

Overrides:

createPredictedLabel in class PredictionModel

setParameter

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

Throws:

OperatorException
