PRISM: Topology-Aware Cross-Modal Imputation for Modality-Deficient Federated Graph Learning

Zekai Chen, Miao Zhang, Jiayang Xing +4

Multimodal federated graph learning (MM-FGL) aims to collaboratively learn from decentralized graphs with text and images. However, real-world clients may not share a common modali…
