讲座摘要：This study delves into the development and practical application of credit-scoring methods under uncertainty scenarios, with a particular emphasis on aligning with the economic goals of decision-makers. Firstly, we address the challenge of parameter uncertainty, where the precise values needed to calculate model profitability are unknown. We introduce a novel profit-based metric, the worst-case expected minimum cost (WEMC), designed to eprofitability of credit-scoring models when faced with uncertain parameters. Additionally, we present the Worst-Case Conditional Value-at-Risk (WCVaR) as a measure of potential losses when applying a classification model in credit scoring with fluctuating cost parameters. Leveraging these metrics, we develop a multi-objective feature selection framework aimed at optimizing model performance by minimizing both costs and risks. The practicality and economic benefits of this framework are demonstrated through empirical analysis. Furthermore, we investigate the effects of predictive uncertainty on the volatility of profits in credit scoring. To address this, we propose a profit-driven uncertainty estimation method that incorporates the economic considerations of decision-makers. This method is applied within a classification with rejection framework, and our empirical results confirm the effectiveness and practical value of the proposed approach in enhancing the robustness of credit scoring models.
