Deciphering Spatio-Temporal Graph Forecasting: A Causal Lens and Treatment

NeurIPS 2023poster

Spatio-Temporal Graph (STG) forecasting is a fundamental task in many real-world applications. Spatio-Temporal Graph Neural Networks have emerged as the most popular method for STG forecasting, but they often struggle with temporal out-of-distribution (OoD) issues and dynamic spatial causation. In t…
