Core Concepts
Transformers and Large Language Models (LLMs) have demonstrated significant potential in capturing complex spatio-temporal dependencies and contextual patterns in human mobility data, enabling accurate prediction of population movements during epidemics.
Abstract
This paper provides a comprehensive survey of recent advancements in leveraging machine learning techniques, particularly Transformer models and Large Language Models (LLMs), for predicting human mobility patterns during epidemics. Understanding how people move during epidemics is essential for modeling the spread of diseases and devising effective response strategies.
The paper first introduces the key human mobility modeling tasks, including generation and prediction. It then discusses the contributions of Transformers in addressing the inherent complexities involved in modeling human mobility dynamics during epidemics. Transformers, with their attention mechanism, have shown superior performance in capturing spatio-temporal dependencies and contextual patterns in textual and mobility data, enabling accurate prediction of future locations and crowd flows.
Furthermore, the paper highlights the recent surge in the development of LLMs tailored specifically for high-fidelity human mobility simulation and forecasting. These models, trained on massive corpora of mobility data paired with auxiliary information, demonstrate the capability to generate plausible mobility trajectories for entire populations under various policy and disease conditions.
The paper also addresses the challenges and limitations of these advanced modeling techniques, particularly in ensuring their applicability and reproducibility in resource-constrained settings, such as low- and middle-income countries (LMICs). It emphasizes the importance of adapting these models to local contexts, integrating local datasets, and fostering collaboration to improve performance and reliability.
Overall, the paper underscores the critical role of machine learning, specifically Transformers and LLMs, in enhancing our understanding of disease dynamics and informing public health interventions during epidemics. The continued progress in this field holds promise for improving epidemiological modeling and supporting more effective and equitable epidemic control strategies worldwide.
