We trained a CrabNet model using data from the Materials Project, optimizing its hyperparameters with the Adaptive Experimentation (Ax) Platform (). After training, this model was used to predict the energy above hull and is_theoretical property for the superconductors in question. For the is_theoretical property, a value close to 1 indicates that similar compounds have not been synthesized previously, and their synthesis would represent a new exploration in the chemical space. A value close to 0, on the other hand, suggests that similar compounds have been synthesized before, and their synthesis would be considered exploitation. These values are under the is_theoretical column in Table .
