Abstract

This paper investigates the problem of meta-clustering real-world retail datasets based on possibility and rough set theories. We propose a crisp then, a soft meta-clustering methods and we compare and analyze the results of both methods using real-world retail datasets. The main aim of this paper is to prove the performance gain of the soft meta-clustering method compared to the crisp one. Our novel methods combine the advantages of the meta-clustering process and the k-modes method under possibilistic and rough frameworks. Our approaches perform a double clustering (or meta-clustering) using two datasets that depend on each other consisting of the retail datasets. It uses for the meta-clustering a modified version of the k-modes method. For the new crisp meta-clustering method, we use the possibilistic k-modes (PKM) and for the soft method, the k-modes under possibilitic and rough frameworks (KM-PR) is applied.
