Researchers have introduced H$^2$EDL, a novel deep learning model designed for hierarchical classification tasks. This model addresses the challenge of structured ambiguity in fine-grained recognition by developing uncertainty representations that capture both leaf-level classes and intermediate concepts. H$^2$EDL achieves this by interpreting its parameters in two ways: as a hierarchical classifier that maintains consistency across label tree levels and as a tree-structured hyper-opinion that quantifies belief without over-specialization. The model demonstrated a significant reduction in calibration error on benchmark datasets like FGVC-Aircraft and DERM12345, with improvements increasing at deeper hierarchy levels and with larger training budgets.
