Researchers have introduced the Exponential Convex Calibration Dimension (CCdim) to analyze the complexity of multi-label classification and binary segmentation tasks. This new metric, applied to the Jaccard score, reveals that achieving exact calibration requires an exponential number of prediction coordinates. The study also provides polynomial-dimensional approximation guarantees and a novel transfer method from F-1 surrogates to Jaccard surrogates, offering practical alternatives for managing regret. AI
