A Survey on Algorithmic Interventions in Opinion Dynamics
Atsushi Miyauchi, Yuko Kuroki, Federico Cinus +2
Social media platforms have become critical infrastructures for public communication, where large-scale interaction can both support socially beneficial collective pressure and amp…
Graph-Regularized Sparse Autoencoders for LLM Safety Steering
Jehyeok Yeon, Federico Cinus, Yifan Wu +1
Sparse autoencoders (SAEs) are increasingly used to extract activation directions for inference-time steering, but their standard sparsity objective treats latent features as indep…
Auditing LLM Editorial Bias in News Media Exposure
Marco Minici, Cristian Consonni, Federico Cinus +1
Large Language Models (LLMs) increasingly act as gateways to web content, shaping how millions of users encounter online information. Unlike traditional search engines, whose retri…
Online Minimization of Polarization and Disagreement via Low-Rank Matrix Bandits
Federico Cinus, Yuko Kuroki, Atsushi Miyauchi +1
We study the problem of minimizing polarization and disagreement in the Friedkin-Johnsen opinion dynamics model under incomplete information. Unlike prior work that assumes a stati…
Uncovering the Sociodemographic Fabric of Reddit
Federico Cinus, Corrado Monti, Paolo Bajardi +1
Understanding the sociodemographic composition of online platforms is essential for accurately interpreting digital behavior and its societal implications. Yet, current methods oft…
Minimizing Polarization and Disagreement in the Friedkin-Johnsen Model with Unknown Innate Opinions
Federico Cinus, Atsushi Miyauchi, Yuko Kuroki +1
The bulk of the literature on opinion optimization in social networks adopts the Friedkin-Johnsen (FJ) opinion dynamics model, in which the innate opinions of all nodes are known:…
Engagement-Driven Content Generation with Large Language Models
Erica Coppolillo, Federico Cinus, Marco Minici +2
Large Language Models (LLMs) demonstrate significant persuasive capabilities in one-on-one interactions, but their influence within social networks, where interconnected users and…
Uncovering Coordinated Cross-Platform Information Operations Threatening the Integrity of the 2024 U.S. Presidential Election Online Discussion
Marco Minici, Luca Luceri, Federico Cinus +1
Information Operations (IOs) pose a significant threat to the integrity of democratic processes, with the potential to influence election-related online discourse. In anticipation…
Exposing Cross-Platform Coordinated Inauthentic Activity in the Run-Up to the 2024 U.S. Election
Federico Cinus, Marco Minici, Luca Luceri +1
Coordinated information operations remain a persistent challenge on social media, despite platform efforts to curb them. While previous research has primarily focused on identifyin…
Link Polarity Prediction from Sparse and Noisy Labels via Multiscale Social Balance
Marco Minici, Federico Cinus, Francesco Bonchi +1
Signed Graph Neural Networks (SGNNs) have recently gained attention as an effective tool for several learning tasks on signed networks, i.e., graphs where edges have an associated…
Navigating Multidimensional Ideologies with Reddit's Political Compass: Economic Conflict and Social Affinity
Ernesto Colacrai, Federico Cinus, Gianmarco De Francisci Morales +1
The prevalent perspective in quantitative research on opinion dynamics flattens the landscape of the online political discourse into a traditional left--right dichotomy. While this…
Rebalancing Social Feed to Minimize Polarization and Disagreement
Federico Cinus, Aristides Gionis, Francesco Bonchi
Social media have great potential for enabling public discourse on important societal issues. However, adverse effects, such as polarization and echo chambers, greatly impact the b…
Cascade-based Echo Chamber Detection
Marco Minici, Federico Cinus, Corrado Monti +2
Despite echo chambers in social media have been under considerable scrutiny, general models for their detection and analysis are missing. In this work, we aim to fill this gap by p…
A Challenging 7-Fold Tiling Puzzle
Theo P. Schaad
A quasiperiodic 7-fold rhombic tiling is constructed with an iterative substitution scheme. The inflation factor is 5.04892..., the square of the longer diagonal of a regular hepta…
