The graph edit distance, GED(g i;q), is the minimum number of graph edit operations that modify g istep-by-step to q(or vise versa), and a graph edit operation can be vertex/edge insertion, deletion, or relabeling. Our choice of GED as the ... WebAug 1, 2024 · A widely used measure is the graph edit distance (GED), which, intuitively, is defined as the minimum amount of distortion that has to be applied to a source graph in order to transform it into a target graph. The main advantage of GED is its flexibility and sensitivity to small differences between the input graphs.
