protected QuickFix	createToBinominalFix(java.lang.String labelName) Creates a quickfix to convert to nominal.
protected QuickFix	createToNumericalFix(java.lang.String labelName) Creates a quickfix to convert to numerical.
protected java.util.Collection<QuickFix>	getFixesForClassificationWhenRegressionSupported() This method has to return a collection of quick fixes which are appropriate when regression is supported and the data needs classification.
protected java.util.Collection<QuickFix>	getFixesForPolynomialClassificationWhenBinominalSupported() This has to return a list of appropriate quick fixes in the case, that only binominal labels are supported but the data contains polynomials.
protected java.util.List<QuickFix>	getFixesForRegressionWhenClassificationSupported(AttributeMetaData labelMD) This method has to return a collection of quick fixes which are appropriate when classification is supported and the data needs regression.

protected void checkLabelPreconditions(ExampleSetMetaData metaData)

getFixesForRegressionWhenClassificationSupported

protected java.util.List<QuickFix> getFixesForRegressionWhenClassificationSupported(AttributeMetaData labelMD)

This method has to return a collection of quick fixes which are appropriate when classification is supported and the data needs regression. The default implementation will return fixes for discretization.

getFixesForClassificationWhenRegressionSupported

protected java.util.Collection<QuickFix> getFixesForClassificationWhenRegressionSupported()

This method has to return a collection of quick fixes which are appropriate when regression is supported and the data needs classification.

getFixesForPolynomialClassificationWhenBinominalSupported

protected java.util.Collection<QuickFix> getFixesForPolynomialClassificationWhenBinominalSupported()

This has to return a list of appropriate quick fixes in the case, that only binominal labels are supported but the data contains polynomials.

createToBinominalFix

protected QuickFix createToBinominalFix(java.lang.String labelName)

Creates a quickfix to convert to nominal.

Parameters:

labelName - If null, regular attributes will be converted. Otherwise the special attribute with the given name will be converted.

createToNumericalFix

protected QuickFix createToNumericalFix(java.lang.String labelName)

Creates a quickfix to convert to numerical.

Parameters:

labelName - If null, regular attributes will be converted. Otherwise the special attribute with the given name will be converted.

createLearnerError

protected void createLearnerError(java.lang.String description,
                                  java.util.List<? extends QuickFix> list)
