Clustering, chance, and statistical mechanicsMarta Luksza1, Michael Lässig2, and •Johannes Berg31Max Planck Institut für molekulare Genetik, Berlin — 2Institut für Theoretische Physik, Universität zu Köln — 3Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

Clustering a set of points in a high-dimensional space is a core method of statistical data analysis. We consider the problem of clustering in random data: Given a set of randomly distributed vectors, how likely do some of them form a cluster with a given cluster score? This cluster p-value is crucial to assess the statistical significance of clusters found in real data. We use a mapping to a disordered spin-model to analytically solve the random clustering problem and discuss applications to the analysis of gene expression patterns.
