Machine Learning for Chinese Corporate Fraud Prediction: Segmented Models Based on Optimal Training Windows
Published 2025-05-01“…Based on a three-stage experiment, we first find that the random forest classifier has the best performance in predicting corporate fraud among 17 machine learning models. We then implement the sliding time window approach to handle population drift, and the optimal training window found demonstrates the existence of population drift in fraud detection and the need to address it for improved model performance. …”
