“…Pre-training based molecular representation learning has shown remarkable performance across various molecular understanding tasks, such as drug discovery (Pinzi & Rastelli, 2019;Adelusi et al, 2022), molecular property prediction (Luo et al, 2022;Liu et al, 2022b;Zhou et al, 2023;Yu et al, 2023) and reaction prediction (Gastegger et al, 2021;Schwaller et al, 2021). Early approaches tend to model 1D SMILES (Wang et al, 2019;Guo et al, 2021;Honda et al, 2019) or 2D graphs (Li et al, 2021;Lu et al, 2021;Fang et al, 2022b;Xia et al, 2022). More recently, there has been a growing interest in 3D molecular data, with its inclusion of 3D structure information providing more comprehensive information of molecules.…”
