Outline

This paper presents a method to generate and utilize synthetic datasets based on partial differential equations (PDEs) to support spatiotemporal graph machine learning modeling research. We generate datasets using three PDEs to model various disaster and hazard phenomena such as epidemics, atmospheric particles, and tsunamis, and benchmark the performance of several machine learning models using the epidemic datasets. We also show that pre-training with synthetic datasets improves model performance on real epidemic data. The source codes of the proposed methodology and the three generated datasets are available on GitHub.

Takeaways, Limitations

Takeaways:
Contributes to solving the problem of lack of spatiotemporal graph datasets based on PDEs.
Provides a dataset that can be used to model various disasters and risk phenomena.
Suggesting the possibility of improving real data model performance through pre-training using synthetic datasets.
Provides methods for creating datasets and benchmarks tailored to individual requirements.
Limitations:
The currently provided dataset is limited to synthetic data. Analysis of differences from real data is required.
Further research is needed on the generalizability and limitations of the proposed PDEs model.
Benchmarking of various machine learning models is limited to the epidemic dataset. Additional experiments on other datasets are needed.
