Fundamental Concepts of
Fuzzy Systems
This chapter examines the nature of fuzzy logic as a method of making
implications with approximate or vague concepts and continues through
the development of approximate reasoning techniques used in fuzzy expert
and decision support systems. The nature of fuzzy implication methods
is contrasted with probabilities, showing how the two approaches model
different aspects of uncertainty. In the final sections of the chapter we look at
fuzzy rule-based decision systems and see how they are intimately connected
to the process of knowledge discovery and rule induction. This tutorial on
fuzzy logic and fuzzy systems provides the foundation needed to understand
how knowledge discovery mechanisms such as clustering ...
