WebOptimal transport. Optimal transport (OT) [33] is a natural type of divergence for registration problems because it accounts for the underlying geometry of the space. In Euclidean settings, OT gives rise to a metric known as the Wasserstein distance W(µ,⌫) which measures the minimum effort WebThe learned attention matrices are also dense and lacks interpretability. We propose Graph Optimal Transport (GOT), a principled framework that germinates from recent …
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 ...
