Prior Knowledge-enhanced Spatio-temporal Epidemic Forecasting

arXiv:2602.22270v2 Announce Type: replace Abstract: Spatio-temporal epidemic forecasting is critical for public health management, yet existing methods often struggle with insensitivity to weak epidemic signals, over-simplified spatial relations, and unstable parameter estimation. To address these challenges, we propose the Spatio-Temporal priOr-aware Epidemic Predictor (STOEP), a novel hybrid framework that integrates implicit spatio-temporal priors and explicit expert priors. STOEP consists of three key components: (1) Case-aware Adjacency Learning (CAL), which dynamically adjusts mobility-b

Why this matters
Why now

The continuous evolution of AI in epidemiological modeling coincides with the ongoing need for more robust public health tools post-pandemic, leveraging advancements in machine learning to address past challenges.

Why it’s important

Improved epidemic forecasting directly impacts public health management, resource allocation, and economic stability by providing more accurate and timely insights into disease spread, reducing the impact of future outbreaks.

What changes

The integration of implicit spatio-temporal priors and explicit expert priors into epidemic forecasting models like STOEP offers a more nuanced and accurate approach compared to previous oversimplified methods, leading to better predictive power.
