| Descrizione: | This pyramidal clustering method generalizes hierarchies by allowing non-disjoint classes at a given level instead a partition. Moreover, the clusters of the pyramid are intervals of a total order on the set being clustered, hence pyramids constitute an intermediate model between the tree and the lattice structures. This method allows moreover to cluster more complex data than the tabular model allows to process, by considering variation on the values taken by the variables. Each cluster formed is defined not only by the set of its elements (i.e. its extent) but also by a symbolic object, which describes its properties (its intent). In this paper we propose a new algorithm CAPS to built a symbolic pyramid, this algorithm in an extension to symbolic case of the algorithm CAP proposed in [Diday 1984] to the symbolic case. An example is presented to illustrate the effectiveness of the proposed algorithm and we also present a free software for this algorithm. |
