Outsmarting quantum chemistry through transfer learning

This work demonstrates empirical potentials based on Deep Neural Networks can surpass the accuracy of Density Functional Theory (DFT) by using Transfer Learning: A potential is first trained to reproduce a large quantity of DFT data, and then fine-tuned by partially retraining to ultra-high-fidelity Coupled-Cluster calculations. The result is the best-to-date empirical model of small organic molecules – far more accurate than traditional Force Fields, and far faster than ab-initio simulation.
