On the nature of mixed-type features in materials datasets
<p>We provide four crystalline materials datasets that contain both numerical and categorical features of materials.</p> <ol> <li>The Lattice dataset [1,2] contains 1,439 binary AB body-centered cubic crystals, as described by 12 numerical and 9 categorical variables. The lattice constant is considered as the physical property of interest.</li> <li>The TC dataset [2,3] contains 101 binary alloys of transition and rare earth metals, as described by 15 numerical and 17 categorical features. The Curie temperature (TC) is considered as the property of interest.</li> <li>The Octet binary materials dataset [4] contains 82 materials, as described by 11 numerical and 2 categorical features. The difference in LDA energy between RS and ZB (∆E = E(RS) − E(ZB)) in eV is considered as the physical property of interest.</li> <li>The Fm3m dataset [5] contains 239 binary compounds collected from the Materials Project, as described by 12 numerical and 17 categorical variables. The formation of energy is considered as the physical property of interest.</li> </ol> <p>References:</p> <p>[1] K. Takahashi, L. Takahashi, J. D. Baran, and Y.
