All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible

public class AttributeSelectionPanel
extends JPanel

Creates a panel that displays the attributes contained in a set of instances, letting the user toggle whether each attribute is selected or not (eg: so that unselected attributes can be removed before classification).
Besides the All, None and Invert button one can also choose attributes which names match a regular expression (Pattern button). E.g. for removing all attributes that contain an ID and therefore unwanted information, one can match all names that contain "id" in the name:

 (.*_id_.*|.*_id$|^id$)
 

This does not match e.g. "humidity", which could be an attribute we would like to keep.
