To test featurizers and demonstrate our recent data processing developments, we selected the simplest 1:1 equiatomic compound cases, similar to the study done a decade ago, but with a more challenging subset -intermetallics. (Compositionally unrestricted data for common structure types often could be easily segregated with self-reiterated parameters such as electronegativity.) The selected intermetallic data is available below in Table . The CIFs in this work were extracted from 2023/2024 versions of PCD. In this study, we limited the dataset to the elements we use in our intermetallic research, provided in Figure .
