Additionally, the adversarial group calibration for the cis-trans region shows very low miscalibration even for smaller group sizes, indicating high calibration accuracy (Figure ). The other posthoc calibration also produces similar results, which is shown in Figure . Building on the energy uncertainty analysis, we extend our evaluation to forces by quantifying the uncertainty regarding the norm of the force vector derived as the energy gradient. Figure These patterns mirror those observed for energy uncertainties, confirming that regions with high force uncertainty correspond to underrepresented areas in the configurational space. Figure demonstrates a strong positive correlation between force uncertainty and prediction error, underscoring the reliability of the uncertainty estimates. Low-error, low-uncertainty clusters, predominantly consisting of trans conformers, are clearly distinguishable from high-error, high-uncertainty regions, which are largely associated with cis conformers and interpolation points. This distinction shows the effectiveness of force uncertainty predictions in pinpointing configurations that require additional sampling to enhance model performance.
