Abstract

Despite the tremendous advances achieved over the past years by deep learning techniques, the latest risk prediction models for industrial applications still rely on highly handtuned stage-wised statistical learning tools, such as gradient boosting and random forest methods. Different from images or languages, real-world financial data are high-dimensional, sparse, noisy and extremely imbalanced, which makes deep neural network models particularly challenging to train and fragile in practice. In this work, we propose DeRisk, an effective deep learning risk prediction framework for credit risk prediction on real-world financial data. DeRisk is the first deep risk prediction model that outperforms statistical learning approaches deployed in our company’s production system. We also perform extensive ablation studies on our method to present the most critical factors for the empirical success of DeRisk.

Complexity vs Empirical Score

  • Math Complexity: 4.0/10
  • Empirical Rigor: 8.0/10
  • Quadrant: Street Traders
  • Why: The paper is heavily implementation-focused, describing a multi-stage pipeline with data preprocessing, separate training, and fine-tuning on real-world financial datasets, with extensive ablation studies and production comparison, showing high empirical rigor. While it references deep learning architectures like Transformers, the mathematical exposition is relatively light, focusing more on the framework design and practical techniques rather than dense theoretical derivations.
