Researchers propose a model for Federated Multimodal Knowledge Graph Completion (FedMKGC) to predict missing links in decentralized knowledge graphs without sharing sensitive information.
The proposed framework, MMFeD3-HidE, addresses challenges such as incomplete entity embeddings and client heterogeneity in FedMKGC.
MMFeD3-HidE consists of a Hyper-modal Imputation Diffusion Embedding model (HidE) for recovering multimodal distributions and Multimodal Federated Dual Distillation (MMFeD3) for transferring knowledge between clients and the server.
Experiments on the proposed benchmark demonstrate the effectiveness, semantic consistency, and convergence robustness of MMFeD3-HidE for Federated Multimodal Knowledge Graph Completion.
