Population synthesis with geographic coordinates
Jacopo Lenti, Lorenzo Costantini, Ariadna Fosch +3
It is increasingly important to generate synthetic populations with explicit coordinates rather than coarse geographic areas, yet no established methods exist to achieve this. One…
Bias and Identifiability in the Bounded Confidence Model
Claudio Borile, Jacopo Lenti, Valentina Ghidini +2
Opinion dynamics models such as the bounded confidence models (BCMs) describe how a population can reach consensus, fragmentation, or polarization, depending on a few parameters. C…
Causal Modeling of Climate Activism on Reddit
Jacopo Lenti, Luca Maria Aiello, Corrado Monti +1
Climate activism is crucial in stimulating collective societal and behavioral change towards sustainable practices through political pressure. Although multiple factors contribute…
Variational Inference of Parameters in Opinion Dynamics Models
Jacopo Lenti, Fabrizio Silvestri, Gianmarco De Francisci Morales
Despite the frequent use of agent-based models (ABMs) for studying social phenomena, parameter estimation remains a challenge, often relying on costly simulation-based heuristics.…
Likelihood-Based Methods Improve Parameter Estimation in Opinion Dynamics Models
Jacopo Lenti, Corrado Monti, Gianmarco De Francisci Morales
We show that a maximum likelihood approach for parameter estimation in agent-based models (ABMs) of opinion dynamics outperforms the typical simulation-based approach. Simulation-b…
Political Context of the European Vaccine Debate on Twitter
Giordano Paoletti, Lorenzo Dall'Amico, Kyriaki Kalimeri +5
At the beginning of the COVID-19 pandemic, fears grew that making vaccination a political (instead of public health) issue may impact the efficacy of this life-saving intervention,…
Global misinformation spillovers in the online vaccination debate before and during COVID-19
Jacopo Lenti, Kyriaki Kalimeri, André Panisson +4
Anti-vaccination views pervade online social media, fueling distrust in scientific expertise and increasing vaccine-hesitant individuals. While previous studies focused on specific…
Ensemble of Opinion Dynamics Models to Understand the Role of the Undecided in the Vaccination Debate
Jacopo Lenti, Giancarlo Ruffo
We present three models used to describe the recruitment of the undecided population by pro-vax and no-vax factions. Starting from real-world data of Facebook pages, we compare thr…
