WebNov 9, 2024 · Graph Matching via Optimal Transport. The 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 increasingly important due to it's applications in operations research, computer vision, neuroscience, and more. WebIn order to make up for the above shortcoming, a domain adaptation based on graph and statistical features is proposed in the papaer. This method uses convolutional neural network (CNN) extracting features with rich semantic information to dynamically construct graphs, and further introduces graph optimal transport (GOT) to align topological ...
