The data sets used in this work consist of crystal structure-lattice energy pairs at three different levels of accuracy and computational complexity in their energy evaluation. The lowest level was evaluated using an atomic multipole-based force field (described below). The intermediate level consists of periodic GGA DFT energies using the Perdew-Burke-Ernzerhof (PBE) functional. While most of the relevant physics is already accounted for in these GGA calculations, for a better treatment of the effect of electron exchange and correlation on the ranking of crystal structures, DFT calculations with PBE0 hybrid exchange-correlation functional were performed as the high level.
