Graph optimal transport
WebIn this sense, direct fusion will destroy the inherent spatial structure of different modal embeddings. To overcome this challenge, we revisit multi-modal KGE from a distributional alignment perspective and propose optimal transport knowledge graph embeddings (OTKGE). Specifically, we model the multi-modal fusion procedure as a transport plan ... Web20240629 [ICML-20] Graph Optimal Transport for Cross-Domain Alignment.
