Uses
Direct Use
The base model can be used for generating meaningful features/embeddings of bulk structures without further training. This model is ideal if finetuned for narrowdown tasks.
Downstream Use
This model can be used with fientuning for property prediction, classification or extractions.
Bias, Risks, and Limitations
Model was trained only on bulk structures (n0w0f/MatText - pretrain2m - dataset).
The pertaining dataset is a subset of the materials deposited in the NOMAD archive. We queried only 3D-connected structures (i.e., excluding 2D materials, which often require special treatment) and, for consistency, limited our query to materials for which the bandgap has been computed using the PBE functional and the VASP code.
