Abstract

Networks are often used to represent the relations among the variables of a dynamical system. The properties of network topology are usually exploited to understand the organization of the system. Nevertheless, the dynamical organization of a system might considerably differ from its topological one. In this paper, we describe a method to identify “relevant subsets” of variables. The variables belonging to a relevant subset should be strongly integrated and should have a much weaker interaction with the other system variables. Extending previous works on neural networks, an information-theoretic measure is introduced, i.e., the Dynamical Cluster Index, in order to identify candidate relevant subsets. The method solely relies on observations of the variables’ values in time.

Notes

  1. 1.

    Results presented in a contribution currently under review.

  2. 2.

    As an ongoing work, we are experimenting with a genetic algorithm for searching the CRS with highest DCI value for each size.

  3. 3.

    The following three examples has already been described in [13], however in this contribution we emphasize different aspects w.r.t. previous work.
