• A Machine Learning Approach to Audit Modification Risk Prediction in Financial Reporting: Methods, Data, and Human-Centered Challenges (2026) · Journal of risk and financial management · doi

  Prior fraud-detection studies rely on raw numeric ratios, which limit interpretability. Most approaches frame the problem as a purely algorithmic classification task and offer limited interpretability for auditors, regulators, and decision-makers. The study identifies the need for a human-interpretable approach to audit modification risk prediction.
