机器学习势能面

Machine Learning Potential Energy Surfaces

Oliver T. Unke, Markus Meuwly

摘要:

机器学习技术可用于表示反应化学系统的高维势能面。两种这样的方法基于再生核希尔伯特空间表示或基于深度神经网络。相对于参考数据,它们可以达到低于1 kcal/mol的精度,并且可以用于化学动力学的研究。本文简要介绍了它们的结构和几个典型实例。

英文摘要:

Machine Learning techniques can be used to represent high-dimensional potential energy surfaces for reactive chemical systems. Two such methods are based on a reproducing kernel Hilbert space representation or on deep neural networks. They can achieve a sub-1 kcal/mol accuracy with respect to reference data and can be used in studies of chemical dynamics. Their construction and a few typical examples are briefly summarized in the present contribution.
