“…In recent years, machine learning (ML) has been applied to the development of interatomic potentials. [41][42][43][44][45][46][47][48][49][50][51][52] Unlike the CBOPs mentioned above, machine learning interatomic potentials (ML-IAPs) do not rely on fixed mathematical expressions but instead learn the mathematical representation of the potential energy surface (PES) via training, which allows for more accurate predictions of energy, forces, and so on. For example, Deringer and Csányi built a Gaussian approximation potential (GAP) for liquid and amorphous carbon that showed close-to-DFT accuracy.…”

“…51 Hedman et al used deep learning to train neural network potentials on the nine-carbon allotrope dataset (CA-9), which reproduced ab initio results with high accuracy. 52 Finally, Rowe et al developed the GAP-17 potential for graphene using the GAP model 46 and, most recently, the GAP-20 potential for various crystalline phase carbon and amorphous carbon, 50 including dispersion corrections and long-range interactions. Although current ML-IAPs have shown excellent accuracy in predicting static and dynamic properties of carbon allotropes, there is still a clear lack of testing related to the prediction of mechanical properties.…”
