Abstract:

In this paper is presented a new method for clustering of objects described by nominal attributes. The method is based on the set theory. There are introduced a definition of conditions’ perturbation for each attribute and a measure of clusters’ perturbations. Next, there is defined a measure of clusters’ concentration as well as a measure of cluster’s distance. These two measures resorted to compute an evaluation of clusters’ set. In the paper the new definitions are elucidated by examples, and there is considered a case of data series clustering problem as an illustrative example.
