Unsupervised Graph Domain Adaptation (UGDA) aims to achieve effective performance in unlabeled target domains by leveraging labeled source domain graphs despite distribution shifts.
SLOGAN (Sparse Causal Discovery with Generative Intervention) is a novel approach proposed to address the challenges faced by existing UGDA methods in yielding suboptimal results due to causal-spurious features and global alignment strategies.
SLOGAN utilizes sparse causal modeling and dynamic intervention mechanisms to achieve stable graph representation transfer by disentangling causal features, compressing domain-dependent correlations, and breaking local spurious couplings through generative intervention.
Extensive experiments on real-world datasets show that SLOGAN outperforms existing baselines, demonstrating its effectiveness in unsupervised graph domain adaptation.
