Given a query graph and database of corpus graphs, retrieval system aims to deliver the most relevant graphs. Graph based on subgraph matching has wide variety applications, e.g., molecular fingerprint detection, circuit design, software analysis, question answering. In such is graph, if (perfectly or approximately) graph. Existing neural models compare node embeddings query-corpus pairs, compu...

With ever growing databases containing multimedia data, indexing has become a necessity to avoid a linear search. We propose a novel technique for indexing multimedia databases in which entries can be represented as graph structures. In our method, the topological structure of a graph as well as that of its subgraphs are represented as vectors whose components correspond to the sorted laplacian...
