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…
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…
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…
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 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…
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…
On-line detection of qualitative dynamical changes in nonlinear systems: the resting-oscillation case
Ying Tang, Alessio Franci, Romain Postoyan
Motivated by neuroscience applications, we introduce the concept of qualitative detection, that is, the problem of determining on-line the current qualitative dynamical behavior (e…
Implementing robust neuromodulation in neuromorphic circuits
Fernando Castaños, Alessio Franci
We introduce a methodology to implement the physiological transition {between distinct neuronal spiking modes} in electronic circuits composed of resistors, capacitors and transist…
A Realization Theory for Bio-inspired Collective Decision-Making
Alessio Franci, Vaibhav Srivastava, Naomi Ehrich Leonard
The collective decision-making exhibited by animal groups provides enormous inspiration for multi-agent control system design as it embodies several features that are desirable in…
Realization of nonlinear behaviors from organizing centers
Alessio Franci, Rodolphe Sepulchre
Borrowing the concept of organizing center from singularity theory, the paper proposes a methodology to realize nonlinear behaviors such as switches, relaxation oscillators, or bur…
