[2507.00031] Enhancing Spatio-Temporal Forecasting with Spatial Neighbourhood Fusion:A Case Study on COVID-19 Mobility in Peru
Summary
This paper presents a novel Spatial Neighbourhood Fusion technique to enhance spatio-temporal forecasting of COVID-19 mobility in Peru, demonstrating improved predictive accuracy.
Why It Matters
Understanding human mobility is crucial for managing epidemic responses. This study offers a new method to improve forecasting accuracy, which can inform public health strategies during crises. The findings could be applied to other regions and contexts, enhancing global epidemic preparedness.
Key Takeaways
- Introduces Spatial Neighbourhood Fusion (SPN) to enhance mobility forecasting.
- Achieves up to 9.85% reduction in mean squared error (MSE) for forecasts.
- Demonstrates the importance of spatial smoothing in predictive modeling.

In this work, we leverage a large-scale spatio-temporal dataset collected from Peru's national Digital Contact Tracing (DCT) application during the COVID-19 pandemic to forecast mobility flows across urban regions. A key challenge lies in the spatial sparsity of hourly mobility counts across hexagonal grid cells, which limits the predictive power of conventional time series models. To address this, we propose a lightweight and model-agnostic Spatial Neighbourhood Fusion (SPN) technique that...
