The Open Catalyst project, which aims to promote the development of new catalysts, has provided two open DFT-MD databases: Open Catalyst 2020 (OC20) and Open Catalyst 2022 (OC22). The type-embedding mechanism 80,81 was used to construct a pre-trained model from OC20 and OC22. This enabled the parameters of the embedding network to be shared among all element species, reducing the computational time required for the training of the NNP.
