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 matching problem. In our proposed framework, we use Optimal Transport (OT) for graph matching, where a transport plan T 2Rn m is WebThe graph matching problem seeks to find an alignment between the nodes of two graphs that minimizes the number of adjacency disagreements. Solving the graph matching is …

We present a novel framework based on optimal transport for the challenging problem of comparing graphs. Specifically, we exploit the probabilistic distribution of smooth graph signals defined with respect to the graph topology. This allows us to derive an explicit expression of the Wasserstein distance between graph signal ...
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.
