Classification Through Regression:Unlock the True Potential of Your Labels
summary
Argues that recasting some classification tasks as regression or ordinal problems measurably lowers risk and overconfidence: implements bilinear cross entropy and real-world cross entropy for asymmetric misclassification costs, uses ordinal regression (K−1 binary heads, ranking consistency fixes) and soft/fuzzy labels to improve calibration, and notes a recent balanced MSE for long-tailed regression. Provides a decision diagram and cookbook tips and reports confusion matrices that move errors nearer the diagonal and better-ordered feature clusters.
