Prompted by this observation, the reference dataset used to fit the GAP-20 model was recomputed, using DFT calculations with moreconsistent reciprocal-space sampling than was used in the original training data. (b) bcc atomization energy for updated GAP-20 model (GAP-20U); the better regularization of the model reduces the magnitude of the fluctuations, and the bcc atomization energy remains high. (a) bcc atomization energy for the original GAP-20 model, showing a bcc carbon minimum below the atomization energy of graphite. [Extracted from the article]
