We assessed the reliability of force uncertainty predictions through miscalibration curves and adversarial group calibration to verify their reliability. Miscalibration curves compare predicted uncertainties with actual errors for both the test set and the cis-trans interpolation region. Initial analysis reveals significant underconfidence in force uncertainty predictions, differing from the trends observed for energy uncertainties. The MACE values of 0.37 for both cases indicate a need for calibration (Figure ).
