In Figure surface of 3d, 4d, and 5d TMOs. The MAE values for 3d systems for the 0th and 3rd orders are 0.12 and 0.14 eV respectively; for 4d systems, the values are 0.24 and 0.35 eV respectively; for 5d systems, the values are 0.18 and 0.41 eV respectively. The R² values for all systems for the 0th and 3rd orders are all better than 0.95.
