提出五维框架,评估信贷风险模型的可解释性。

Unlocking the Black Box: A Five-Dimensional Framework for Evaluating Explainable AI in Credit Risk

  • 构建包含五维度的可解释性评估框架。
  • 证明复杂模型在可解释技术下仍可满足监管要求。
  • 适合金融风控与AI可解释性研究者参考。

金融机构在建模和风险管控中面临挑战:需在先进机器学习模型(如神经网络)的预测能力与监管机构(如美国货币监理署、消费者金融保护局)要求的可解释性之间取得平衡。本文旨在弥合这类‘黑箱’模型与可解释性工具(如LIME、SHAP)之间的应用鸿沟。作者分析了这些工具在不同模型上的适用性,表明更复杂的高预测性能模型可通过SHAP与LIME实现同等水平的可解释性。此外,本文提出一个全新的五维评估框架——内在可解释性、全局解释、局部解释、一致性、复杂性,提供一种超越简单准确率指标的精细评估方法。研究证实,借助现代可解释性技术,高性能机器学习模型可在受监管金融环境中应用,并为模型性能与可解释性之间的权衡提供了结构化评估路径。

原文摘要 · Abstract (English)

The financial industry faces a significant challenge modeling and risk portfolios: balancing the predictability of advanced machine learning models, neural network models, and explainability required by regulatory entities (such as Office of the Comptroller of the Currency, Consumer Financial Protection Bureau). This paper intends to fill the gap in the application between these "black box" models and explainability frameworks, such as LIME and SHAP. Authors elaborate on the application of these frameworks on different models and demonstrates the more complex models with better prediction powers could be applied and reach the same level of the explainability, using SHAP and LIME. Beyond the comparison and discussion of performances, this paper proposes a novel five dimensional framework evaluating Inherent Interpretability, Global Explanations, Local Explanations, Consistency, and Complexity to offer a nuanced method for assessing and comparing model explainability beyond simple accuracy metrics. This research demonstrates the feasibility of employing sophisticated, high performing ML models in regulated financial environments by utilizing modern explainability techniques and provides a structured approach to evaluate the crucial trade offs between model performance and interpretability.
