Nonequilibrium steady-state dynamics of Markov processes on graphs
Stefano Crotti, Thomas Barthel, Alfredo Braunstein
We propose an analytic approach for the steady-state dynamics of Markov processes on locally tree-like graphs. It is based on time-translation invariant probability distributions f…
Metabolic coordination and phase transitions in spatially distributed multi-cellular systems
Krishnadev Narayanankutty, José Antonio Pereiro-Morejon, Arián Ferrero-Fernández +7
During overflow metabolism, cells excrete glycolytic byproducts when growing under aerobic conditions in a seemingly wasteful fashion. While potentially advantageous for microbes w…
Matrix Product Belief Propagation for reweighted stochastic dynamics over graphs
Stefano Crotti, Alfredo Braunstein
Stochastic processes on graphs can describe a great variety of phenomena ranging from neural activity to epidemic spreading. While many existing methods can accurately describe typ…
A Density Consistency approach to the inverse Ising problem
Alfredo Braunstein, Giovanni Catania, Luca Dall'Asta +1
We propose a novel approach to the inverse Ising problem which employs the recently introduced Density Consistency approximation (DC) to determine the model parameters (couplings a…
Optimality in self-organized molecular sorting
Marco Zamparo, Donatella Valdembri, Guido Serini +4
We introduce a simple physical picture to explain the process of molecular sorting, whereby specific proteins are concentrated and distilled into submicrometric lipid vesicles in e…
Loop corrections in spin models through density consistency
Alfredo Braunstein, Giovanni Catania, Luca Dall'Asta
Computing marginal distributions of discrete or semidiscrete Markov random fields (MRFs) is a fundamental, generally intractable problem with a vast number of applications in virtu…
A method to reduce the rejection rate in Monte Carlo Markov Chains
Carlo Baldassi
We present a method for Monte Carlo sampling on systems with discrete variables (focusing in the Ising case), introducing a prior on the candidate moves in a Metropolis-Hastings sc…
Inference for interacting linear waves in ordered and random media
P. Tyagi, A. Pagnani, F. Antenucci +2
A statistical inference method is developed and tested for pairwise interacting systems whose degrees of freedom are continuous angular variables, such as planar spins in magnetic…
Generalized belief propagation for the magnetization of the simple cubic Ising model
Alessandro Pelizzola
A new approximation of the cluster variational method is introduced for the three-dimensional Ising model on the simple cubic lattice. The maximal cluster is, as far as we know, th…
Variational approximations for stationary states of Ising-like models
Alessandro Pelizzola
We introduce a new variational approach to the stationary state of kinetic Ising-like models. The approach is based on the cluster expansion of the entropy term appearing in a func…
Large deviations of cascade processes on graphs
F. Altarelli, A. Braunstein, L. Dall'Asta +1
Simple models of irreversible dynamical processes such as Bootstrap Percolation have been successfully applied to describe cascade processes in a large variety of different context…
Stochastic optimization by message passing
Fabrizio Altarelli, Alfredo Braunstein, Abolfazl Ramezanpour +1
Most optimization problems in applied sciences realistically involve uncertainty in the parameters defining the cost function, of which only statistical information is known before…
The stochastic matching problem
Fabrizio Altarelli, Alfredo Braunstein, Abolfazl Ramezanpour +1
The matching problem plays a basic role in combinatorial optimization and in statistical mechanics. In its stochastic variants, optimization decisions have to be taken given only s…
Palette-colouring: a belief-propagation approach
Alessandro Pelizzola, Marco Pretti, Jort van Mourik
We consider a variation of the prototype combinatorial-optimisation problem known as graph-colouring. Our optimisation goal is to colour the vertices of a graph with a fixed number…
