Optimal transport graph matching
Webthis graph construction process is considered “dynamic”. By representing the entities in both domains as graphs, cross-domain alignment is naturally formulated into a graph … WebOptimal transportation provides a means of lifting distances between points on a geometric domain to distances between signals over the domain, expressed as probability distributions. On a graph, transportation problems can be used to express challenging tasks involving matching supply to demand with minimal shipment expense; in discrete …

WebGraph Optimal Transport. The recently proposed GOT [35] graph distance uses optimal transport in a different way. This relies on a probability distribution X, the graph signal of X[44, 15], over functions on the vertices of X. This distribution is a multivariate Gaussian, with mean zero, whose variance-covariance matrix is a pseudo-inverse Ly X WebPlus, the learned attention matrices are often dense and difficult to interpret. We propose Graph Optimal Transport (GOT), a principled framework that builds upon recent advances in Optimal Transport (OT). In GOT, cross-domain alignment is formulated as a graph matching problem, by representing entities as a dynamically-constructed graph.
WebIn order to use graph matching (or optimal transport) in large-scale problems, researchers propose the mini-batch OT (Optimal Transport) [57], mini- batch UOT (Unbalanced Optimal Transport) [58], and mini- batch POT (Partial Optimal Transport) [30] methods to improve efficiency while guaranteeing accuracy.
