WekaClassifier(Attribute label)

WekaClassifier(java.lang.String name, Attribute label, weka.classifiers.Classifier classifier)

Method Summary

void	applyModelForInstance(weka.core.Instance instance, Example e, Attribute predictedLabelAttribute) Classifies ervery weka instance and sets the result as predicted label of the current example.
boolean	equals(java.lang.Object o) Returns true iff the given object has the same class.
java.lang.String	getName() The default implementation returns the classname without package.
java.awt.Component	getVisualisationComponent(IOContainer container) Returns a label that displays the ResultObjectAdapter.toResultString() result encoded as html.
void	performPrediction(ExampleSet exampleSet, Attribute predictedLabel) Subclasses should iterated through the given example set and set the prediction for each example.
void	readPredictionModelData(java.io.ObjectInputStream in) Reads the model data (without label).
java.lang.String	toResultString() The default implementation simply returns the result of the method Object.toString().
java.lang.String	toString()
void	writePredictionModelData(java.io.ObjectOutputStream out) Writes the model data (without label).

public WekaClassifier(Attribute label)

WekaClassifier

public WekaClassifier(java.lang.String name,
                      Attribute label,
                      weka.classifiers.Classifier classifier)

Method Detail

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

applyModelForInstance

public void applyModelForInstance(weka.core.Instance instance,
                                  Example e,
                                  Attribute predictedLabelAttribute)

Classifies ervery weka instance and sets the result as predicted label of the current example.

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

readPredictionModelData

public void readPredictionModelData(java.io.ObjectInputStream in)
                             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

getName

public java.lang.String getName()

Description copied from class: ResultObjectAdapter

The default implementation returns the classname without package.

Specified by:

getName in interface ResultObject

Overrides:

getName in class ResultObjectAdapter

toString

public java.lang.String toString()

Overrides:

toString in class PredictionModel

toResultString

public java.lang.String toResultString()

Description copied from class: ResultObjectAdapter

The default implementation simply returns the result of the method Object.toString().

Specified by:

toResultString in interface ResultObject

Overrides:

toResultString in class ResultObjectAdapter

getVisualisationComponent

public java.awt.Component getVisualisationComponent(IOContainer container)

Description copied from class: ResultObjectAdapter

Returns a label that displays the ResultObjectAdapter.toResultString() result encoded as html. Please note that the returned label 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:

getVisualisationComponent in interface ResultObject

Overrides:

getVisualisationComponent in class ResultObjectAdapter

equals

public boolean equals(java.lang.Object o)

Description copied from class: AbstractModel

Returns true iff the given object has the same class.

Overrides:

equals in class AbstractModel
