Ergodic and Metastable Behavior of Stochastic Popularity Dynamics in Social Networks
Chiara Ravazzi, Paolo Frasca, Gaya Cocca
This paper studies popularity dynamics in social networks, where users' engagement with competing channels is driven by intrinsic content quality, social influence, and popularity…
Model Predictive Control for Coupled Adoption-Opinion Dynamics
Martina Alutto, Qiulin Xu, Fabrizio Dabbene +2
This paper investigates an optimal control problem for an adoption-opinion model that couples opinion dynamics with a compartmental adoption framework on a multilayer network to st…
On a Coupled Adoption-Opinion Framework for Competing Innovations
Martina Alutto, Fabrizio Dabbene, Angela Fontan +2
In this paper, we propose a two-layer adoption-opinion model to study the diffusion of two competing technologies within a population whose opinions evolve under social influence a…
Optimal policy design for innovation diffusion: shaping today's incentives for transforming the future
Lisa Piccinin, Valentina Breschi, Chiara Ravazzi +2
In this paper, we propose a new framework for the design of incentives aimed at promoting innovation diffusion in social influence networks. In particular, our framework relies on…
Modeling and Control of Sustainable Transitions through Opinion-Behavior Coupling in Heterogeneous Networks
Martina Alutto, Sofia Bellotti, Fabrizio Dabbene +1
Understanding how sustainable behaviors spread within heterogeneous societies requires the integration of behavioral data, social influence mechanisms, and structured approaches to…
Predictive Control Strategies for Sustaining Innovation Adoption on Multilayer Social Networks
Martina Alutto, Qiulin Xu, Fabrizio Dabbene +2
In this paper, we propose a novel compartmental model that couples adoption dynamics and opinion formation over a multilayer network, and we address an optimal control problem with…
Innovation diffusion dynamics toward long-term behavioral shifts
Lisa Piccinin, Valentina Breschi, Chiara Ravazzi +2
Sustainable technologies and services can play a pivotal role in the transition to "greener" habits. Their widespread adoption is thus crucial, and understanding how to foster this…
Optimal Policy Design for Repeated Decision-Making under Social Influence
Chiara Ravazzi, Valentina Breschi, Paolo Frasca +2
In this paper, we present a novel model to characterize individual tendencies in repeated decision-making scenarios, with the goal of designing model-based control strategies that…
A Coupled Friedkin-Johnsen Model of Popularity Dynamics in Social Media
Gaya Cocca, Paolo Frasca, Chiara Ravazzi
Popularity dynamics in social media depend on a complex interplay of social influence between users and popularity-based recommendations that are provided by the platforms. In this…
Power minimization and resource allocation in HetNets with uncertain channel-gains
Gabriel O. Ferreira, Chiara Ravazzi, Fabrizio Dabbene +1
We propose an optimization problem to minimize the base stations transmission powers in OFDMA heterogeneous networks, while respecting users' individual throughput demands. The dec…
Optimal policy design for decision problems under social influence
Valentina Breschi, Chiara Ravazzi, Paolo Frasca +2
This paper focuses on describing the impact of policy actions on individuals' opinions in the presence of social and external influences toward proposing preliminary nudging strate…
