7.1 The Vocabulary of Fuzzy Clustering

If you exclude mathematical equations, the vocabulary of fuzzy cluster-

ing is surprisingly sparse. In fact, much of the underlying terminology

related to cluster configuration, membership, and overlap has already

been covered in the chapters on fuzzy logic fundamentals. A review of

some vocabulary terms used in fuzzy clustering, however, will make read-

ing and understanding the material in this chapter somewhat easier. It

is, however, not always possible, while maintaining an uncluttered and

coherent discussion of the clustering process, to ensure that every term

is introduced before it is used.
