Researchers have developed a new framework called Decoupled Relation Subspace Alignment (DRSA) to improve the performance of Graph Foundation Models (GFMs) on complex, multi-domain heterogeneous graphs. Existing methods struggle with feature shifts and relation gaps between different data types, leading to issues like "Type Collapse." DRSA addresses this by decoupling feature semantics from relation structures, using a dual-relation subspace projection and a feature-structure decoupled representation to better handle variations and enhance cross-domain knowledge transfer.
