When these weighting functions output constant, we can infer that the cost function is a linear transformation of AUC. W AUC. The idea of weighting thresholds in AUC is first described by [ Bilevel optimization is a classical algorithm for operations research. B.1 Main Idea of Experiments Our experiments mainly explore the following three problems: Traditional AUC is inconsistent with the cost-related metrics and cannot be used in cost-sensitive learning scenarios. From the experimental results in our paper, we can see that most AUC optimization methods do not minimize the misclassification cost. Ultimately, the misclassification cost of the decision is not acceptable.
