All Implemented Interfaces:

public class ClassifierPanel
extends javax.swing.JPanel
implements Explorer.CapabilitiesFilterChangeListener, Explorer.ExplorerPanel, Explorer.LogHandler

0* This panel allows the user to select and configure a classifier, set the attribute of the current dataset to be used as the class, and evaluate the classifier using a number of testing modes (test on the training data, train/test on a percentage split, n-fold cross-validation, test on a separate split). The results of classification runs are stored in a result history so that previous results are accessible.

Field Detail

MODEL_FILE_EXTENSION

The filename extension that should be used for model files

PMML_FILE_EXTENSION

public static java.lang.String PMML_FILE_EXTENSION

The filename extension that should be used for PMML xml files

Constructor Detail

ClassifierPanel

public ClassifierPanel()

Creates the classifier panel

Method Detail

setLog

public void setLog(Logger newLog)

Sets the Logger to receive informational messages

Specified by:

setLog in interface Explorer.LogHandler

Parameters:

newLog - the Logger that will now get info messages

setInstances

public void setInstances(Instances inst)

Tells the panel to use a new set of instances.

Specified by:

setInstances in interface Explorer.ExplorerPanel

Parameters:

inst - a set of Instances

processClassifierPrediction

public static void processClassifierPrediction(Instance toPredict,
                                               Classifier classifier,
                                               Evaluation eval,
                                               Instances plotInstances,
                                               FastVector plotShape,
                                               FastVector plotSize)

Process a classifier's prediction for an instance and update a set of plotting instances and additional plotting info. plotInfo for nominal class datasets holds shape types (actual data points have automatic shape type assignment; classifier error data points have box shape type). For numeric class datasets, the actual data points are stored in plotInstances and plotInfo stores the error (which is later converted to shape size values)

Parameters:

toPredict - the actual data point

classifier - the classifier

eval - the evaluation object to use for evaluating the classifier on the instance to predict

plotInstances - a set of plottable instances

plotShape - additional plotting information (shape)

plotSize - additional plotting information (size)

setUpVisualizableInstances

public static Instances setUpVisualizableInstances(Instances trainInstances)

Sets up the structure for the visualizable instances. This dataset contains the original attributes plus the classifier's predictions for the class as an attribute called "predicted+WhateverTheClassIsCalled".

Parameters:

trainInstances - the instances that the classifier is trained on

Returns:

a new set of instances containing one more attribute (predicted class) than the trainInstances

capabilitiesFilterChanged

public void capabilitiesFilterChanged(Explorer.CapabilitiesFilterChangeEvent e)

method gets called in case of a change event

Specified by:

capabilitiesFilterChanged in interface Explorer.CapabilitiesFilterChangeListener

Parameters:

e - the associated change event

setExplorer

public void setExplorer(Explorer parent)

Sets the Explorer to use as parent frame (used for sending notifications about changes in the data)

Specified by:

setExplorer in interface Explorer.ExplorerPanel

Parameters:

parent - the parent frame

getExplorer

public Explorer getExplorer()

returns the parent Explorer frame

Specified by:

getExplorer in interface Explorer.ExplorerPanel

Returns:

the parent

getTabTitle

public java.lang.String getTabTitle()

Returns the title for the tab in the Explorer

Specified by:

getTabTitle in interface Explorer.ExplorerPanel

Returns:

the title of this tab

getTabTitleToolTip

public java.lang.String getTabTitleToolTip()

Specified by:

getTabTitleToolTip in interface Explorer.ExplorerPanel

Returns:

the tooltip of this tab
