Exploring Concept Subspace for Self-explainable Text-Attributed Graph Learning

Xiaoxue Han, Libo Zhang, Zining Zhu +1

We introduce Graph Concept Bottleneck (GCB) as a new paradigm for self-explainable text-attributed graph learning. GCB maps graphs into a subspace, concept bottleneck, where each c…
