The test split of the dataset Alex_MP-20. This dataset contains structures from the Alexandria (Schmidt et al. 2022) and MP-20 (Materials Project 2020) datasets. Data has been modified as follows: Exclude structures containing the elements Tc, Pm, or any element with atomic number 84 or higher. Relax structures with DFT using a PBE functional in order to have consistent energies. For the training set, remove any structure with more than 20 atoms inside the unit cell. For the training set, remove any structure with energy above the hull higher than 0.1 eV/atom.
