Package weka.gui.explorer

Class ExperimentPanel

  • All Implemented Interfaces:
    ImageObserver, MenuContainer, Serializable, EventListener, Accessible, weka.gui.explorer.Explorer.CapabilitiesFilterChangeListener, weka.gui.explorer.Explorer.ExplorerPanel, weka.gui.explorer.Explorer.LogHandler
    public class ExperimentPanel
extends JPanel
implements weka.gui.explorer.Explorer.CapabilitiesFilterChangeListener, weka.gui.explorer.Explorer.ExplorerPanel, weka.gui.explorer.Explorer.LogHandler
    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 perform an Experiment (like in the Experimenter) with this Classifier/Dataset combination. The results of the experiment runs are stored in a result history so that previous results are accessible.

    Based on the ClassifierPanel code (by Len Trigg, Mark Hall and Richard Kirkby).
