Similarly, when predicting shear modulus, we observed that the KRR model performed the best (MAE 9.019 GPa), while the overall performance of the RF, KRR, MLP, GBM, GPR, and SVR models are almost identical (see Fig. ). We also see that the MAE error for predicting shear modulus is relatively lower compared to bulk modulus. Similar to the bulk modulus, with the KRR model, the global attributes "density" and volume per atom are found to be the most important features. In general, the importance of structural attributes is crucial for predicting shear modulus as well (see supplementary information Fig.
