Dimensionality reduction of neuronal degeneracy reveals two interfering physiological mechanisms
Arthur Fyon, Alessio Franci, Pierre Sacré +1
Neuronal systems maintain stable functions despite large variability in their physiological components. Ion channel expression, in particular, is highly variable in neurons exhibit…
Neuromorphic Control of a Pendulum
Raphael Schmetterling, Fulvio Forni, Alessio Franci +1
We illustrate the potential of neuromorphic control on the simple mechanical model of a pendulum, with both event-based actuation and sensing. The controller and the pendulum are r…
Multi-topic belief formation through bifurcations over signed social networks
Anastasia Bizyaeva, Alessio Franci, Naomi Ehrich Leonard
We propose and analyze a nonlinear dynamic model of continuous-time multi-dimensional belief formation over signed social networks. Our model accounts for the effects of a structur…
Sustained oscillations in multi-topic belief dynamics over signed networks
Anastasia Bizyaeva, Alessio Franci, Naomi Ehrich Leonard
We study the dynamics of belief formation on multiple interconnected topics in networks of agents with a shared belief system. We establish sufficient conditions and necessary cond…
Breaking indecision in multi-agent, multi-option dynamics
Alessio Franci, Martin Golubitsky, Ian Stewart +2
How does a group of agents break indecision when deciding about options with qualities that are hard to distinguish? Biological and artificial multi-agent systems, from honeybees a…
Control of Multistability through Local Sensitivity Analysis: Application to Cellular Decision-making Networks
Rodrigo Moreno-Morton, Alessio Franci
Control of multistable dynamical system has important applications, from physics to biology. Here, we attack this problem from the perspective of local sensitivity analysis. We dev…
Switching transformations for decentralized control of opinion patterns in signed networks: application to dynamic task allocation
Anastasia Bizyaeva, Giovanna Amorim, Maria Santos +2
We propose a new decentralized design method to control opinion patterns on signed networks of agents making decisions about two options and to switch the network from any opinion…
The correlated variability control problem: a dominant approach
Marcela Ordorica Arango, Alessio Franci
Given a population of interconnected input-output agents repeatedly exposed to independent random inputs, we talk of correlated variability when agents' outputs are variable (i.e.,…
In-phase oscillations from the cooperation of cellular and network positive feedback in synaptically-coupled oscillators
Omar Juarez-Alvarez, Alessio Franci
We study the emergent dynamics of a network of synaptically coupled slow-fast oscillators. Synaptic coupling provides a network-level positive feedback mechanism that cooperates wi…
Equivalence of Linear Complementarity Problems: Theory and Application to Nonsmooth Bifurcations
Felix Miranda-Villatoro, Fernando Castaños, Alessio Franci
Linear complementarity problems provide a powerful framework to model nonsmooth phenomena in a variety of real-world applications. In dynamical control systems, they appear coupled…
Tuning Cooperative Behavior in Games with Nonlinear Opinion Dynamics
Shinkyu Park, Anastasia Bizyaeva, Mari Kawakatsu +2
We examine the tuning of cooperative behavior in repeated multi-agent games using an analytically tractable, continuous-time, nonlinear model of opinion dynamics. Each modeled agen…
Feedback design of spatially-distributed filters with tunable resolution
Alessio Franci
We derive gain-tuning rules for the positive and negative spatial-feedback loops of a spatially-distributed filter to change the resolution of its spatial band-pass characteristic…
Control of Agreement and Disagreement Cascades with Distributed Inputs
Anastasia Bizyaeva, Timothy Sorochkin, Alessio Franci +1
For a group of autonomous communicating agents, the ability to distinguish a meaningful input from disturbance, and come to collective agreement or disagreement in response to that…
Analysis and control of agreement and disagreement opinion cascades
Alessio Franci, Anastasia Bizyaeva, Shinkyu Park +1
We introduce and analyze a continuous time and state-space model of opinion cascades on networks of large numbers of agents that form opinions about two or more options. By leverag…
Patterns of Nonlinear Opinion Formation on Networks
Anastasia Bizyaeva, Ayanna Matthews, Alessio Franci +1
When communicating agents form opinions about a set of possible options, agreement and disagreement are both possible outcomes. Depending on the context, either can be desirable or…
Nonlinear Opinion Dynamics with Tunable Sensitivity
Anastasia Bizyaeva, Alessio Franci, Naomi Ehrich Leonard
We propose a continuous-time multi-option nonlinear generalization of classical linear weighted-average opinion dynamics. Nonlinearity is introduced by saturating opinion exchanges…
A notion of equivalence for linear complementarity problems with application to the design of non-smooth bifurcations
Fernando Castaños, Félix Miranda-Villatoro, Alessio Franci
Many systems of interest to control engineering can be modeled by linear complementarity problems. We introduce a new notion of equivalence between linear complementarity problems…
A model-independent theory of consensus and dissensus decision making
Alessio Franci, Martin Golubitsky, Anastasia Bizyaeva +1
We develop a model-independent framework to study the dynamics of decision-making in opinion networks for an arbitrary number of agents and an arbitrary number of options. Model-in…
Social decision-making driven by artistic explore-exploit tension
Kayhan Ozcimder, Biswadip Dey, Alessio Franci +3
We studied social decision-making in the rule-based improvisational dance , where dancers make in-the-moment compositional choices. Rehearsals provided…
Cellular switches orchestrate rhythmic circuits
Guillaume Drion, Alessio Franci, Rodolphe Sepulchre
Small inhibitory neuronal circuits have long been identified as key neuronal motifs to generate and modulate the coexisting rhythms of various motor functions. Our paper highlights…
Multi-agent decision-making dynamics inspired by honeybees
Rebecca Gray, Alessio Franci, Vaibhav Srivastava +1
When choosing between candidate nest sites, a honeybee swarm reliably chooses the most valuable site and even when faced with the choice between near-equal value sites, it makes hi…
Robust and tunable bursting requires slow positive feedback
Alessio Franci, Guillaume Drion, Rodolphe Sepulchre
We highlight that the robustness and tunability of a bursting model critically relies on currents that provide slow positive feedback to the membrane potential. Such currents have…
Excitable behaviors
Rodolphe Sepulchre, Guillaume Drion, Alessio Franci
This chapter revisits the concept of excitability, a basic system property of neurons. The focus is on excitable systems regarded as behaviors rather than dynamical systems. By thi…
