WebAug 9, 2024 · Graph similarity measurement, which computes the distance/similarity between two graphs, arises in various graph-related tasks. Recent learning-based methods lack interpretability, as they directly transform interaction information between two graphs into one hidden vector and then map it to similarity. To cope with this problem, this … WebGraph similarity learning for change-point detection in dynamic networks. no code yet • 29 Mar 2024. The main novelty of our method is to use a siamese graph neural network architecture for learning a data-driven graph similarity function, which allows to effectively compare the current graph and its recent history.

WebGraph similarity search is among the most important graph-based applications, e.g. finding the chemical compounds that are most similar to a query compound. Graph similarity/distance computation, such as … WebGraph similarity is usually defined based on structural similarity measures such as GED or MCS [ 19 ]. Traditional exact GED calculation is known to be NP-complete and cannot scale to graphs with more than tens of nodes. Thus, classic approximation algorithms are proposed to mitigate this issue. florist in ida grove ia
