Synergy as a warning sign of transitions: the case of the two-dimensional Ising model
Daniele Marinazzo, Leonardo Angelini, Mario Pellicoro +1
We consider the formalism of information decomposition of target effects from multi-source interactions, i.e. the problem of defining redundant and synergistic components of the in…
Natural clustering: the modularity approach
L. Angelini, D. Marinazzo, M. Pellicoro +1
We show that modularity, a quantity introduced in the study of networked systems, can be generalized and used in the clustering problem as an indicator for the quality of the solut…
Clustering data by inhomogeneous chaotic map lattices
L. Angelini, F. De Carlo, C. Marangi +2
A new approach to clustering, based on the physical properties of inhomogeneous coupled chaotic maps, is presented. A chaotic map is assigned to each data-point and short range cou…
Phase ordering in chaotic map lattices with conserved dynamics
Leonardo Angelini, Mario Pellicoro, Sebastiano Stramaglia
Dynamical scaling in a two-dimensional lattice model of chaotic maps, in contact with a thermal bath, is numerically studied. The model here proposed is equivalent to a conserved I…
Variational method and duality in the 2D square Potts model
L. Angelini, M. Pellicoro, I. Sardella +1
The ferromagnetic q-state Potts model on a square lattice is analyzed, for q>4, through an elaborate version of the operatorial variational method. In the variational approach prop…
