Abstract

An action is defined as controlling or changing some of attribute values in an information system to achieve desired result. An action reduct is a minimal set of attribute values distinguishing a favorable object from other objects. We use action reducts to formulate necessary actions. The action suggested by an action reduct induces changes of decision attribute values by changing the condition attribute values to the distinct patterns in action reducts.
