Figure presents the evolution of aleatoric and epistemic uncertainty across the three scenarios (baseline, halogen-agnostic, and noisy halogens). Panels A to C show the uncertainty distributions by atom type (boxplots), which include the halogens (fluorine, chlorine, bromine, iodine), as well as carbon, nitrogen, oxygen, and sulfur, categorized by hybridization state (e.g., "C-SP" for sphybridized carbon). Panels D to E provide detailed histograms of uncertainty distributions for the halogen atoms.
