Graph Out-of-Distribution Generalization via Causal Intervention

1 code implementation18 Feb 2024 Qitian Wu, Fan Nie, Chenxiao Yang, TianYi Bao, Junchi Yan

In this paper, we adopt a bottom-up data-generative perspective and reveal a key observation through causal analysis: the crux of GNNs' failure in OOD generalization lies in the latent confounding bias from the environment.
