Abstract

We report in this paper about our practice of frequent pattern discovery algorithms in the context of mining biological data related to genomic alterations in cancer. A number of frequent item set methods have already been successfully applied to various biological data obtained from large scale analyses (see for instance [4] for SAGE data, [20,22,26] for gene expression data), and all of these have to face the peculiarity of such data wrt standard basket analysis data, namely that the number of observations is low wrt the number of attributes.
