Generalized Entropies for Clustering, e.g., in Molecular Evolution — •Kay Hamacher — TU Darmstadt, 64287 Darmstadt, Germany

Entropy is a key concept in information theory. Analysis of empirical data is often improved by relying on (relative) entropies. In this talk I want to describe current progress in clustering approaches by optimization techniques [1-2] applied to entropy distances via generalized entropy concepts [3], in phylogenies [4,5], finite-size effects in empirical data [6], and in molecular design [7].
