Constructor Detail

PMMLNormalizeTranslator

public PMMLNormalizeTranslator()

Creates a new empty translator to be initialized by the #initializeFrom(LocalTransformations, boolean) or #initializeFrom(TransformationDictionary, boolean) method.

PMMLNormalizeTranslator

public PMMLNormalizeTranslator(AffineTransConfiguration trans,
                               DerivedFieldMapper mapper)

Creates an initialized translator that can export its configuration.

Parameters:

trans - the affine trans configuration * @param mapper mapping data column names to PMML derived field names and vice versa

mapper - mapping data column names to PMML derived field names and vice versa

Method Detail

getAffineTransConfig

public AffineTransConfiguration getAffineTransConfig()

Builds a configuration object for a AffineTransTable.

Returns:

the affine trans configuration

exportToTransDict

public org.dmg.pmml40.TransformationDictionaryDocument.TransformationDictionary exportToTransDict()

Exports the translators state to a new TransformationDictionary element.

Specified by:

exportToTransDict in interface PMMLPreprocTranslator

Returns:

the transformation dictionary containing the preprocessing elements

exportToLocalTrans

public org.dmg.pmml40.LocalTransformationsDocument.LocalTransformations exportToLocalTrans()

Exports the translators state to a new LocalTransformations element.

Specified by:

exportToLocalTrans in interface PMMLPreprocTranslator

Returns:

the local transformations containing the preprocessing elements

initializeFrom

public List<Integer> initializeFrom(org.dmg.pmml40.DerivedFieldDocument.DerivedField[] derivedFields)

Initializes the translator based on a derived field array.

Specified by:

initializeFrom in interface PMMLPreprocTranslator

Parameters:

derivedFields - the derived fields to initialize from

Returns:

a list with the indices of all derived field entries that could be consumed
