Fuzzy Rule Induction

In the preceding chapters we looked at various ways to find patterns in data

using fuzzy database queries and fuzzy clustering. Both of these techniques

provide the knowledge engineer and business analyst with a powerful set

of exploratory facilities. However, they do not generate actual models of

the underlying business process. This is the goal of rule induction. As the

term implies, rule induction creates a knowledge base of fuzzy if-then rules

describing one or more behaviors in a large collection of data. This is a

supervised knowledge discovery approach; that is, you must supply a depen-

dent or outcome variable and a wider set of independent (or working)

variables. Rule induction then finds the functional relationships ...
