Empowering Heterogeneous Graph Foundation Models via Decoupled Relation Alignment

Dimensions overall score 7.0

• Decoupled Relation Subspace Alignment (DRSA) enhances heterogeneous graph foundation models by aligning cross-type interactions and adapting to intra-domain variations. Existing global feature alignment methods (PCA or SVD) enforce a shared feature space blindly, which distorts type-specific semantics and disrupts original topologies, inevitably leading to "Type Collapse" and "Relation Confusion".problem 35%

• ScienceToStartup currently rates this 7.0/10 on the public viability pass. Extensive experiments on multiple real-world benchmark datasets demonstrate that DRSA can be seamlessly integrated as a universal preprocessing module, significantly and consistently enhancing the cross-domain and few-shot knowledge transfer capabilities of state-of-the-art GFMs. A public repository is linked, so build verification can inspect implementation evidence instead of treating the paper as PDF-only.result 35%
