weka.classifiers.Classifier

weka.classifiers.trees.UserClassifier

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, CapabilitiesHandler, Drawable, OptionHandler, RevisionHandler, TechnicalInformationHandler, TreeDisplayListener, VisualizePanelListener

public class UserClassifier
extends Classifier
implements Drawable, TreeDisplayListener, VisualizePanelListener, TechnicalInformationHandler

Interactively classify through visual means. You are Presented with a scatter graph of the data against two user selectable attributes, as well as a view of the decision tree. You can create binary splits by creating polygons around data plotted on the scatter graph, as well as by allowing another classifier to take over at points in the decision tree should you see fit.

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.

getTechnicalInformation

public TechnicalInformation getTechnicalInformation()

Returns an instance of a TechnicalInformation object, containing detailed information about the technical background of this class, e.g., paper reference or book this class is based on.

Specified by:

getTechnicalInformation in interface TechnicalInformationHandler

Returns:

the technical information about this class

getCapabilities

public Capabilities getCapabilities()

Returns default capabilities of the classifier.

Specified by:

getCapabilities in interface CapabilitiesHandler

Overrides:

getCapabilities in class Classifier
