Constructor Detail

SupportVectorMachineModel

public SupportVectorMachineModel(org.w3c.dom.Element model,
                                 Instances dataDictionary,
                                 MiningSchema miningSchema)
                          throws java.lang.Exception

Construct a new SupportVectorMachineModel encapsulating the information provided in the PMML document.

Parameters:

model - the SVM element from the PMML document

dataDictionary - the data dictionary

miningSchema - the mining schema

Throws:

java.lang.Exception - if the model can't be constructed from the PMML

Method Detail

distributionForInstance

public double[] distributionForInstance(Instance inst)
                                 throws java.lang.Exception

Classifies the given test instance. The instance has to belong to a dataset when it's being classified.

Specified by:

distributionForInstance in interface Classifier

Overrides:

distributionForInstance in class AbstractClassifier

Parameters:

inst - the instance to be classified

Returns:

the predicted most likely class for the instance or Utils.missingValue() if no prediction is made

Throws:

java.lang.Exception - if an error occurred during the prediction

getRevision

public java.lang.String getRevision()

Description copied from class: AbstractClassifier

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Overrides:

getRevision in class AbstractClassifier

Returns:

the revision

toString

public java.lang.String toString()

Get a textual description of this SupportVectorMachineModel

Overrides:

toString in class java.lang.Object

Returns:

a description of this SupportVectorMachineModel as a string
