RADD: Retrieval-Augmented Discrete Diffusion for Multi-Modal Knowledge Graph Completion
arXiv:2604.25693v2 Announce Type: replace Abstract: Most multi-modal knowledge graph completion (MMKGC) models use one embedding scorer to conduct both retrieval over the full entity set and final link prediction. We argue that this coupling is a core bottleneck: global high-recall search and local fine-grained disambi
