Abstract

In this paper we propose an improvement of the Ben-Hur algorithm to assess the significance level of the solutions, by introducing a quantitative approach and a statistical test based on the distribution of suitable similarity measures between pairs of clustered projected data. Moreover we propose also a new way to perturb the data, based on random projections into lower dimensional subspaces, that seems to be well-suited to the characteristics (high-dimensionality, redundancy, noise) of genomic and proteomic data.
