arXiv:2604.15838v2 Announce Type: replace Abstract: Distribution shift severely degrades the performance of deep forecasting models. While this issue is well-studied for individual time series, it remains a significant challenge in the spatio-temporal domain. Effective solutions like instance normalization and its variants can mitigate temporal shifts by standardizing statistics. However, distribution shift on a graph is far more complex, involving not only the drift of individual node series but also heterogeneity across the spatial network where different nodes exhibit distinct statistical p
The paper provides an improved method for handling spatio-temporal distribution shifts, a critical challenge in deep forecasting models, and builds upon existing normalization techniques.
Advanced forecasting models are crucial for various critical infrastructure and AI applications, and mitigating distribution shifts directly improves their reliability and applicability across complex real-world data.
This research enhances the robustness of deep forecasting models, particularly in complex spatio-temporal domains, by addressing a fundamental limitation that degrades performance in dynamic environments.
