Webthis end, we propose a contrastive graph matching network (CGMN) for self-supervised graph sim-ilarity learning in order to calculate the similar-ity between any two input graph objects. Specif-ically, we generate two augmented views for each graph in a pair respectively. Then, we employ two strategies, namely cross-view interaction and cross- WebAug 23, 2024 · Matching. Let 'G' = (V, E) be a graph. A subgraph is called a matching M (G), if each vertex of G is incident with at most one edge in M, i.e., deg (V) ≤ 1 ∀ V ∈ G. …

WebNov 11, 2024 · GMN is an extension to GNNs for the purpose of graph similarity learning [ 33 ]. Instead of computing graph representations independently for each graph, GMNs take a pair of graphs as input and compute a similarity score by a cross-graph attention mechanism at the cost of certain computation efficiency. 3. Related Work WebIn order to detect code clones with the graphs we have built, we propose a new approach that uses graph neural networks (GNN) to detect code clones.
