public class ClassifierPanel

extends javax.swing.JPanel

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

public static java.lang.String MODEL_FILE_EXTENSION

The filename extension that should be used for model 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

Parameters:

newLog - the Logger that will now get info messages

setXY_VisualizeIndexes

public void setXY_VisualizeIndexes(int x,
                                   int y)

Set the default attributes to use on the x and y axis of a new visualization object.

Parameters:

x - the index of the attribute to use on the x axis

y - the index of the attribute to use on the y axis

setInstances

public void setInstances(Instances inst)

Tells the panel to use a new set of instances.

Parameters:

inst - a set of Instances

processClassifierPrediction

public static void processClassifierPrediction(Instance toPredict,
                                               Classifier classifier,
                                               Evaluation eval,
                                               FastVector predictions,
                                               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

predictions - a fastvector to add the prediction to

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".

Returns:

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

main

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

Tests out the classifier panel from the command line.

Parameters:

args - may optionally contain the name of a dataset to load.
