Constructor Detail

TreeModel

public TreeModel(Element model,
                 Instances dataDictionary,
                 MiningSchema miningSchema)
          throws Exception

Throws:

Exception

Method Detail

distributionForInstance

public double[] distributionForInstance(Instance inst)
                                 throws 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:

Exception - if an error occurred during the prediction

toString

public String toString()

Overrides:

toString in class Object

graph

public String graph()
             throws Exception

Description copied from interface: Drawable

Returns a string that describes a graph representing the object. The string should be in XMLBIF ver. 0.3 format if the graph is a BayesNet, otherwise it should be in dotty format.

Specified by:

graph in interface Drawable

Returns:

the graph described by a string

Throws:

Exception - if the graph can't be computed

getRevision

public 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

graphType

public int graphType()

Description copied from interface: Drawable

Returns the type of graph representing the object.

Specified by:

graphType in interface Drawable

Returns:

the type of graph representing the object
