1 Introduction
Cluster analysis is a technique for classifying data, i.e., to divide a given dataset into a set of classes or clusters.
The goal is to divide the dataset in such a way ... objects or cases into classes and categories. In classical cluster analysis each datum must be assigned
to exactly one cluster. Fuzzy cluster analysis relaxes this requirement by allowing gradual ... the shape of the cluster. The cluster center is an
instantiation of the attributes used to describe the domain, just as the data points in the dataset to divide.
However, the cluster center is...
