WebGiven a computron M = [G, C] with a generating graph G and connectors set C, we embed it in a metric space that captures similarity of its configuration states as follows: The distance between two cells is set as the shortest-path-length on generating graph between the two vertices occupied by these cells mapped to a unit interval. The ... WebMar 24, 2024 · In many domains where data are represented as graphs, learning a similarity metric among graphs is considered a key problem, which can further …
WebComputing graph similarity is an important task in many graph-related applications such as retrieval in graph databases or graph clustering. While numerous measures have been proposed to capture the similarity between a pair of graphs, Graph Edit Distance (GED) and Maximum Common Subgraphs (MCS) are the two widely used measures in practice. WebJun 30, 2024 · In general, we view similarity as proximity with respect to some metric. A common way of converting a graph metric d into a similarity measure s is to let s (G, H) \coloneqq exp (− β ⋅ d (G, H)) for some constant β > 0. For our considerations the transformation between distance and similarity is irrelevant, so we focus directly on the ...
