This section details the specific gradient-based adversarial attacks (FGSM and PGD) employed to probe model vulnerabilities. It emphasizes the 'plausibility-bounded' nature of perturbations, ensuring attacks remain realistic for financial contexts, and outlines the white-box threat model assumed in the research.
Beyond traditional performance metrics, this category quantifies the financial consequences of adversarial attacks, including Expected Loss (EL), Value-at-Risk (VaR), and Expected Shortfall (ES). It highlights how minor perturbations can significantly alter portfolio loss distributions and influence capital provisioning.
Explore the effectiveness of various defense mechanisms, focusing on PGD adversarial training and lightweight regularization techniques. The analysis covers their impact on clean accuracy, calibration, economic risk mitigation, and the stability of model explanations.
This critical area investigates how adversarial attacks affect the interpretability of models. It quantifies SHAP attribution stability and introduces an LLM-based Semantic Robustness Index (SRI) to detect conceptual shifts in model reasoning, potentially serving as an early warning for robustness issues.

Case Study: Credit Scoring System Under Attack
Challenge: A major bank's credit scoring model, performing well on clean data, was susceptible to minor perturbations in customer income and credit utilization. These subtle changes, while plausible, led to misclassification of high-risk applicants as low-risk.
Solution: Implementing PGD adversarial training significantly improved the model's robustness. The adversarially-trained model maintained high accuracy even under attack, and its ECE was drastically reduced, ensuring more reliable probability estimates.
Impact: The enhanced robustness prevented an estimated 5% increase in portfolio expected loss, safeguarding capital and maintaining regulatory compliance. Explanation stability also improved, reinforcing trust in model decisions even in adversarial scenarios.
