Method Details

initPMML

public static PMML initPMML()

Initializes a PMML object with header information.

Returns:

an initialized PMML object

addDataDictionary

public static void addDataDictionary(Instances trainHeader,
 PMML pmml)

Adds a data dictionary to the supplied PMML object.

Parameters:

trainHeader - the training data header - i.e. the header of the data that enters the buildClassifier() method of the model in question

pmml - the PMML object to add the data dictionary to

getOPTYPE

public static OPTYPE getOPTYPE(int wekaType)

Returns an OPTYPE for a weka attribute type. Note that PMML only supports categorical, continuous and ordinal types.

Parameters:

wekaType - the type of the weka attribute

Returns:

the PMML type

getNameAndValueFromUnsupervisedNominalToBinaryDerivedAttribute

public static String[] getNameAndValueFromUnsupervisedNominalToBinaryDerivedAttribute(Instances train,
 Attribute derived)

Extracts the original attribute name and value from the name of a binary indicator attribute created by unsupervised NominalToBinary. Handles the case where one or more equals signs might be present in the original attribute name.

Parameters:

train - the original, unfiltered training header

derived - the derived attribute from which to extract the original name and value from the name created by NominalToBinary.

Returns:
