Different Kinds of Rules and Systems of Rules

Abstract

Decision rules are mappings from a set of conditions to an outcome. There are many uses for decision rules and even more methods for construction of decision rules. Decision rules are most commonly used in sets. Such sets can be referred to as systems of decision rules. Both decision rules and systems of decision rules can be analyzed with regards to different criteria (cost functions). In this chapter, we provide definitions and basic concepts with regards to decision rules and systems of decision rules.
