@PerspectiveInfo(ID="weka.gui.explorer.attributeselectionpanel",
                 title="Select attributes",
                 toolTipText="Determine relevance of attributes",
                 iconPath="weka/gui/weka_icon_new_small.png")
public class AttributeSelectionPanel
extends AbstractPerspective
implements Explorer.CapabilitiesFilterChangeListener, Explorer.ExplorerPanel, Explorer.LogHandler

This panel allows the user to select and configure an attribute evaluator and a search method, set the attribute of the current dataset to be used as the class, and perform attribute selection using one of two selection modes (select using all the training data or perform a n-fold cross validation---on each trial selecting features using n-1 folds of the data). The results of attribute selection runs are stored in a results history so that previous results are accessible.
