新的HGR框架增强了分子生成和表示学习能力

研究人员开发了一个名为高阶语法表示(HGR)的新框架,以改进分子学习模型。HGR通过以计算高效的方式显式编码高阶拓扑结构(如环系),解决了现有序列和图形式的局限性。该框架将分子拓扑结构序列化为紧凑的生成规则序列,使其与标准序列模型兼容。为了评估HGR,创建了一个名为RingDiv的新基准,包含118万个分子和一个环多样性指数(RDI)来衡量环系覆盖率。使用HGR的模型在分子生成方面表现出卓越的性能,实现了100%的有效性和领先的分布对齐,并在表示学习方面表现出色,在MoleculeNet基准测试中超越了现有基线。 AI

影响 这一新框架有望显著提高化学研究和药物发现中AI模型的效率和准确性。
