Admissible clustering procedures
Lloyd D. Fisher, John W. Van Ness · Biometrika · 1971
Since it is usually impossible to determine a ‘best’ clustering procedure, admissible clustering procedures are suggested. Let A denote some property which should be satisfied by any reasonable procedure either in general or when used in a special application. Any procedure which satisfies A is called A -admissible. Nine admissibility conditions are defined and several standard clustering methods are compared with them.
