Graphretro
Webreaction center identification. 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- WebGraphRetro [13] also adopts a similar framework and generates the reactants by attaching leaving groups to synthons. Dual model [9] proposes a general energy based model framework that integrates both sequence and graph based models, and performs consistent training over forward and backward prediction directions. 3.

WebRetroXpert (Yan et al.,2024) and GraphRetro (Somnath et al.,2024) achieve state-of-the-art performance by decom-posing the retrosynthesis into two sub-problems: i) cen-ter identification and ii) synthon completion, as shown in Fig.1. Center identification increases the model scalability by breaking down the target molecule into virtual synthons WebAug 5, 2024 · As baseline models, we compared our prediction results with five state-of-the-art retrosynthesis models: GLN (conditional graph logic network), 14 G2G (graph to graph), 15 GraphRetro, 16 MEGAN (molecule edit graph attention network), 17 and Augmented Transformer. 25 We denote our method by LocalRetro to emphasize the core idea, local …
