Generalized L-Modularity for Community Detection Beyond Simple Temporal Networks
Victor Brabant, Angela Bonifati, Remy Cazabet
Detecting communities in networks is essential for understanding the mesoscopic organization of complex systems. Interactions in most real-world networks evolve over time and exhib…
Instance Discrimination for Link Prediction
Valentin Cuzin-Rambaud, Mathieu Lefort, Rémy Cazabet
Recently, instance discrimination models have emerged as a major solution for self-supervised learning. Having already demonstrated its effectiveness in the image domain, instance…
Discovering Communities in Continuous-Time Temporal Networks by Optimizing L-Modularity
Victor Brabant, Angela Bonifati, Rémy Cazabet
Community detection is a fundamental problem in network analysis, with many applications in various fields. Extending community detection to the temporal setting with exact tempora…
Longitudinal Modularity, a Modularity for Link Streams
Victor Brabant, Yasaman Asgari, Pierre Borgnat +2
Temporal networks are commonly used to model real-life phenomena. When these phenomena represent interactions and are captured at a fine-grained temporal resolution, they are model…
Y Social: an LLM-powered Social Media Digital Twin
Giulio Rossetti, Massimo Stella, Rémy Cazabet +7
In this paper we introduce Y, a new-generation digital twin designed to replicate an online social media platform. Digital twins are virtual replicas of physical systems that allow…
