Method Detail

main

public static void main(java.lang.String[] argv)

Main method for testing this class.

Parameters:

argv - should contain command line options (see setOptions)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

a string that represents this objects tree.

userCommand

public void userCommand(TreeDisplayEvent e)

Receives user choices from the tree view, and then deals with these choices.

Specified by:

userCommand in interface TreeDisplayListener

Parameters:

e - The choice.

userDataEvent

public void userDataEvent(VisualizePanelEvent e)

This receives shapes from the data view. It then enters these shapes into the decision tree structure.

Specified by:

userDataEvent in interface VisualizePanelListener

Parameters:

e - Contains the shapes, and other info.

graphType

public int graphType()

Returns the type of graph this classifier represents.

Specified by:

graphType in interface Drawable

Returns:

Drawable.TREE

graph

public java.lang.String graph()
                       throws java.lang.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:

A string formatted with a dotty representation of the decision tree.

Throws:

java.lang.Exception - if String can't be built properly.

globalInfo

public java.lang.String globalInfo()

This will return a string describing the classifier.

Returns:

The string.

buildClassifier

public void buildClassifier(Instances i)
                     throws java.lang.Exception

Call this function to build a decision tree for the training data provided.

Specified by:

buildClassifier in class Classifier

Parameters:

i - The training data.

Throws:

java.lang.Exception - if can't build classification properly.

distributionForInstance

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

Call this function to get a double array filled with the probability of how likely each class type is the class of the instance.

Overrides:

distributionForInstance in class Classifier

Parameters:

i - The instance to classify.

Returns:

A double array filled with the probalities of each class type.

Throws:

java.lang.Exception - if can't classify instance.
