ANI-1: an extensible neural network potential with DFT accuracy at force field computational cost [PDF]

open access: yesChemical Science, 2016
We demonstrate how a deep neural network (NN) trained on a data set of quantum mechanical (QM) DFT calculated energies can learn an accurate and transferable atomistic potential for organic molecules containing H, C, N, and O atoms.
