Abstract

We analyze the learning graph-matching algorithm presented in M. Martineau, R. Raveaux, D. Conte, G.Venturini, Learning error-correcting graph matching with a multiclass neural network, Pattern Recognition Letters (2018). Authors propose a new definition of the graph edit distance and also a learning algorithm that deduces some weights on this new graph edit distance. In this commentary, we first show that this new definition of the graph edit distance cannot be considered a distance and then, we discuss how this fact influences on the application of their learning methodology.
