Figure (a) shows the results of the comparison, with measurements of accuracy for both methods presented in the inlaid box. As seen, adding the ML calibration to xTB-sTDA results vastly improves results, reducing the MAE by 66%. For comparison, Figure (b) shows the results of TD-DFT calculations using PBE0 and CAM-B3LYP on the same test set of molecules. As seen, xTB-CC-ML has higher accuracy than TD-DFT calculations for the 11.5k test set, using either R2 or MAE as the metric.
