Graph World Models for Constrained Epidemic Policy Planning

Graph World Models for Constrained Epidemic Policy Planning introduces EpiMind, a graph-factored recurrent state-space model that generates joint policy-conditioned rollouts from regional latent beliefs. The framework uses graph-temporal ADMM to optimize regional interventions, enforce shared-resource feasibility, and evaluate temporal specifications under the learned model. EpiMind achieves a 29% reduction in admission RMSE compared to graph-free dynamics, plans within 1–5% of the best feasible constant policy while guaranteeing shared-budget feasibility, and outperforms all deployable baselines across three resource budgets in real-context evaluation.

An Infectious Disease Spread Simulation Based on Large Language Model Decision Making

Modelling individual decision-making during infectious disease outbreaks is crucial for understanding behavioural dynamics and informing effective public health interventions. Prior work has shown that large language models can simulate realistic human behaviour by generating agent decisions based on demographic prompts and situational context.

Benchmarking Counterfactual Prediction in Epidemic Time Series with Time-Varying Interventions

Deep learning has enabled significant advances in time-series causal inference, yet progress remains constrained by the lack of realistic benchmarks with observable counterfactual outcomes. Existing datasets either rely on real-world observations without ground-truth counterfactuals or on simplified simulations that fail to capture complex causal dynamics.

LLM-powered reasoning in agent-based modeling

arXiv:2607. 06757v1 Announce Type: new Abstract: Agent-based modeling (ABM) has the capability to model millions of individuals and their interactions, which is useful for policy making.
