In essence, static guidance signs within the hub should be designed according to passengers’ pathfinding demand, that is, to provide passengers with accurate …
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 ... Web2.2. Gromov-Wasserstein Optimal Transport Classic optimal transport requires defining a cost function to move samples across domains, which can be difficult to implement for data in different dimensions. Gromov-Wasserstein distance allows for the comparison of distri-butions in different metric spaces by comparing pairwise
