In an apparatus and method for computerized design of fuzzy rules from
training data vectors, a membership function type is selected from a set
of predetermined membership function types, and membership values for the
training data vectors and center of gravity values for the membership
functions are determined in alternation in an iterative method for all
training data vectors and for each membership function. When an abort
criterion is met, then the most recently determined membership functions,
described by the center of gravity values, are employed as rules.
