IntervenSim: Intervention-Aware Social Network Simulation for Opinion Dynamics

This arXiv feed collects multiple papers (Apr 2026) with several security-relevant findings: (1) IntervenSim: an "intervention-aware" social-network simulator that models source-side interventions and crowd feedback to better reproduce event trajectories (improves MAPE 41.6%, DTW 66.9% over prior work); (2) MF-MDP: a micro–macro social simulation framework that models per-agent latent states for long-horizon simulations (code published at github.com/AI4SS/MF-MDP), enabling stable simulations of far more interactions than prior LLM-based approaches; (3) a study releasing a large Brazilian YouTu
