public class ClassifierPanel
extends 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.

setLog
Sets the Logger to receive informational messages- Specified by:
setLog
in interfaceExplorer.LogHandler
- Parameters:
newLog
- the Logger that will now get info messages
-
setInstances
Tells the panel to use a new set of instances.- Specified by:
setInstances
in interfaceExplorer.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 pointclassifier
- the classifiereval
- the evaluation object to use for evaluating the classifier on the instance to predictplotInstances
- a set of plottable instancesplotShape
- additional plotting information (shape)plotSize
- additional plotting information (size)
-
setUpVisualizableInstances
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
method gets called in case of a change event- Specified by:
capabilitiesFilterChanged
in interfaceExplorer.CapabilitiesFilterChangeListener
- Parameters:
e
- the associated change event
-
setExplorer
Sets the Explorer to use as parent frame (used for sending notifications about changes in the data)- Specified by:
setExplorer
in interfaceExplorer.ExplorerPanel
- Parameters:
parent
- the parent frame
-
getExplorer
returns the parent Explorer frame- Specified by:
getExplorer
in interfaceExplorer.ExplorerPanel
- Returns:
- the parent
-
getTabTitle
Returns the title for the tab in the Explorer- Specified by:
getTabTitle
in interfaceExplorer.ExplorerPanel
- Returns:
- the title of this tab
-
getTabTitleToolTip
Returns the tooltip for the tab in the Explorer- Specified by:
getTabTitleToolTip
in interfaceExplorer.ExplorerPanel
- Returns:
- the tooltip of this tab
-
main
Tests out the classifier panel from the command line.- Parameters:
args
- may optionally contain the name of a dataset to load.
