Method Detail

learn

public Model learn(ExampleSet exampleSet)
            throws OperatorException

Description copied from interface: Learner

Trains a model. This method should be called by apply() and is implemented by subclasses.

Specified by:

learn in interface Learner

Throws:

OperatorException

getTechnicalInformation

public weka.core.TechnicalInformation getTechnicalInformation()

Specified by:

getTechnicalInformation in interface weka.core.TechnicalInformationHandler

getWekaClassPath

public java.lang.String getWekaClassPath()

This method is used by the GenericWekaLearner to specify the learners name.

getWekaParameterList

public java.util.List getWekaParameterList()

This method is used by the GenericWekaMetaLearner to specify the learners parameters.

onlyWarnForNonSufficientCapabilities

public boolean onlyWarnForNonSufficientCapabilities()

Returns true.

Overrides:

onlyWarnForNonSufficientCapabilities in class AbstractLearner

supportsCapability

public boolean supportsCapability(LearnerCapability capability)

Description copied from interface: Learner

Checks for Learner capabilities. Should return true if the given capability is supported.

Specified by:

supportsCapability in interface Learner

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator
