Since the test data was obtained from the NOMAD database, a repository of computationally-generated materials, we aimed to evaluate the synthesizability of the superconductors with predicted critical temperatures. To assess their stability, we queried the materials from the Materials Project and obtained their energy above hull values. The lower the energy above hull, the more stable the compound is considered to be. These values are under the predicted_e_above_hull column in Table . Additionally, we obtained the is_theoretical property, which indicates if a material has been reported in the International Crystal Structure Database (ICSD) (i.e. if it has been synthesized previously).
