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
