Class HyperPipes

java.lang.Object
weka.classifiers.Classifier
weka.classifiers.misc.HyperPipes
All Implemented Interfaces:
Serializable, Cloneable, CapabilitiesHandler, OptionHandler, RevisionHandler
public class HyperPipes extends Classifier
Class implementing a HyperPipe classifier. For each category a HyperPipe is constructed that contains all points of that category (essentially records the attribute bounds observed for each category). Test instances are classified according to the category that "most contains the instance".
Does not handle numeric class, or missing values in test cases. Extremely simple algorithm, but has the advantage of being extremely fast, and works quite well when you have "smegloads" of attributes.

Valid options are: 

 -D
  If set, classifier is run in debug mode and
  may output additional info to the console
