Instabilities in Attractor Networks with Fast Synaptic Fluctuations and Partial Updating of the Neurons Activity
J. J. Torres, J. Marro, J. M. Cortes +1
We present and study a probabilistic neural automaton in which the fraction of simultaneously-updated neurons is a parameter, rho (0, 1) . For small rho, there is relaxation toward…
Loop corrections for message passing algorithms in continuous variable models
Bastian Wemmenhove, Bert Kappen
In this paper we derive the equations for Loop Corrected Belief Propagation on a continuous variable Gaussian model. Using the exactness of the averages for belief propagation for…
On Cavity Approximations for Graphical Models
T. Rizzo, B. Wemmenhove, H. J. Kappen
We reformulate the Cavity Approximation (CA), a class of algorithms recently introduced for improving the Bethe approximation estimates of marginals in graphical models. In our new…
Sensitivity, Itinerancy and Chaos in Partly-Synchronized Weighted Networks
J. Marro, J. J. Torres, J. M. Cortes +1
We present exact results, as well as some illustrative Monte Carlo simulations, concerning a stochastic network with weighted connections in which the fraction of nodes that are dy…
Survey propagation at finite temperature: application to a Sourlas code as a toy model
B Wemmenhove, H J Kappen
In this paper we investigate a finite temperature generalization of survey propagation, by applying it to the problem of finite temperature decoding of a biased finite connectivity…
Finitely connected vector spin systems with random matrix interactions
A. Coolen, N. S. Skantzos, I. Perez Castillo +4
We use finite connectivity equilibrium replica theory to solve models of finitely connected unit-length vectorial spins, with random pair-interactions which are of the orthogonal m…
