GRAPHRETRO (Somnath et al.,2024) also considers the atom whose number of at-tached hydrogens changes in the product as a single reaction center. Then, it uses MPN (Gilmer et al.,2024) to model the probability of each bond or atom as a single reaction center. It is worth noting that GRAPHRETRO roughly pro-
