• Abstract summary: EpiGNN is a graph neural network-based model for epidemic forecasting. We develop a Region-Aware Graph (RAGL) that takes transmission risk, geographical dependencies, and temporal information into account. We show that EpiGNN outperforms state-of-the-art baselines by 9.48% in RMSE.

• Abstract: Epidemic forecasting is the key to effective control of epidemic transmission and helps the world mitigate the crisis that threatens public health. To better understand the transmission and evolution of epidemics, we propose EpiGNN, a graph neural network-based model for epidemic forecasting. Specifically, we design a transmission risk encoding module to characterize local and global spatial effects of regions in epidemic processes and incorporate them into the model. Meanwhile, we develop a Region-Aware Graph Learner (RAGL) that takes transmission risk, geographical dependencies, and temporal information into account to better explore spatial-temporal dependencies and makes regions aware of related regions' epidemic situations. The RAGL can also combine with external resources, such as human mobility, to further improve prediction performance. Comprehensive experiments on five real-world epidemic-related datasets (including influenza and COVID-19) demonstrate the effectiveness of our proposed method and show that EpiGNN outperforms state-of-the-art baselines by 9.48% in RMSE.

This paper proposes a STOP-temporal knowledge mining framework, named STOP to model the impact of human mobility and contextual information over large geographic area in different temporal scales. The framework has two modules: (i) S-temporal data and computing infrastructure using fog/edge based architecture; and (ii) S-temporal data analytics module to efficiently extract knowledge from heterogeneous data sources.
