Firing rate distributions in plastic networks of spiking neurons

no code implementations9 Nov 2023 Marina Vegué, Antoine Allard, Patrick Desrosiers

In recurrent networks of leaky integrate-and-fire (LIF) neurons, mean-field theory has proven successful in describing various statistical properties of neuronal activity at equilibrium, such as firing rate distributions.

The determining role of covariances in large networks of stochastic neurons

no code implementations19 Dec 2022 Vincent Painchaud, Patrick Desrosiers, Nicolas Doyon

We tackle this problem by constructing a dynamical model of both the expectations and covariances of the fractions of active and refractory neurons in the network's populations.

Beyond Wilson-Cowan dynamics: oscillations and chaos without inhibition

no code implementations1 Apr 2022 Vincent Painchaud, Nicolas Doyon, Patrick Desrosiers

Fifty years ago, Wilson and Cowan developed a mathematical model to describe the activity of neural populations.

Universality of the stochastic block model

no code implementations11 Jun 2018 Jean-Gabriel Young, Guillaume St-Onge, Patrick Desrosiers, Louis J. Dubé

Mesoscopic pattern extraction (MPE) is the problem of finding a partition of the nodes of a complex network that maximizes some objective function.

Community Detection Stochastic Block Model

Phase transition in the recoverability of network history

1 code implementation25 Mar 2018 Jean-Gabriel Young, Guillaume St-Onge, Edward Laurence, Charles Murphy, Laurent Hébert-Dufresne, Patrick Desrosiers

Network growth processes can be understood as generative models of the structure and history of complex networks.

Finite size analysis of the detectability limit of the stochastic block model

1 code implementation31 Dec 2016 Jean-Gabriel Young, Patrick Desrosiers, Laurent Hébert-Dufresne, Edward Laurence, Louis J. Dubé

We then distinguish the concept of average detectability from the concept of instance-by-instance detectability and give explicit formulas for both definitions.
