Evaluation of Thermochemical Machine Learning for Potential Energy Curves and Geometry Optimization [PDF]

open access: yes, 2021
While many machine learning methods, particularly deep neural networks have been trained for density functional and quantum chemical energies and properties, the vast majority of these methods focus on single-point energies. In principle, such ML methods,
