Abstract
The structural characteristics of clusters are investigated in the partitio
ning process. Two partition functions, which show opposite properties aroun
d the optimal cluster number, are found and a new cluster validity index is
presented based on the combination of these functions. Some properties of
the index function are discussed and numerical examples are presented.
