Abstract

In this paper we consider a clustering problem for a data-points set
$\mathcal{A}$ into disjoint nonempty subsets - clusters, whereby
it is assumed that elements of the set $\mathcal{A}$ are determined by
one or two characteristics. Least square criteria and least absolute deviation criteria are used for
solving the problem. A number of examples illustrating differences
between these criteria are given. Corresponding software support is
developed for the purpose of facilitating scientific or professional
work by using this methodology and approach.

Keywords
