Since the onset of the COVID-19 pandemic, there has been a growing interest in studying epidemiological models. Traditional mechanistic models mathematically describe the transmission mechanisms of infectious diseases. However, they often fall short when confronted with the growing challenges of today. Consequently, Graph Neural Networks (GNNs) have emerged as a progressively popular tool in epidemic research. In this paper, we endeavor to furnish a comprehensive review of GNNs in epidemic tasks and highlight potential future directions. To accomplish this objective, we introduce hierarchical taxonomies for both epidemic tasks and methodologies, offering a trajectory of development within this domain. For epidemic tasks, we establish a taxonomy akin to those typically employed within the epidemic domain. For methodology, we categorize existing work into Neural Models and Hybrid Models. Following this, we perform an exhaustive and systematic examination of the methodologies, encompassing both the tasks and their technical details. Furthermore, we discuss the limitations of existing methods from diverse perspectives and systematically propose future research directions. We envisage that this tutorial will serve as a valuable resource for researchers, delivering a thorough examination of contemporary GNN models in epidemiology, while also illuminating promising avenues for future exploration.
This tutorial is designed for researchers and practitioners from both the graph machine learning and epidemiology communities, who are interested in exploring the application of GNNs in epidemiology. It is recommended that participants possess a foundational knowledge of (un)supervised learning, neural networks, and basic epidemiological concepts. Furthermore, prior experience in graph learning (eg., training a GNN) will be beneficial for attendees.
