FDPFormer introduces a novel axial-prototype transformer architecture specifically designed for financial statements. Unlike generic tabular models, it explicitly models both cross-sectional inconsistencies within a year and multi-year temporal dynamics, crucial for uncovering sophisticated fraud schemes.
Key Architectural Components:
- Table Embedding Layer: Preserves the two-dimensional 'year-metric' structure of financial data.
- Axial Transformer Encoder: Uses feature-axis and time-axis attention to capture both horizontal logical relationships and vertical temporal changes.
- Deception Prototype Extractor: Learns interpretable 'fraud risk prototypes' aligned with audit semantics, providing explainable pattern recognition.
- Two-Stage Training Strategy: Enhances discriminative capability by aligning structural features with audit knowledge through contrastive learning.
Empirical results demonstrate FDPFormer's superior performance in identifying potential fraud risks, particularly in scenarios involving complex, coordinated manipulations. Its unique prototype-based approach also offers auditors unparalleled explainability.
Performance Highlights:
- Achieved the highest Recall(1) (0.690) and AUC (0.745) on real-world A-share firm datasets, outperforming XGBoost and FT-Transformer.
- Significantly improved detection for frauds requiring multi-year, multi-account coordination, such as profit inflation and fictitious assets.
- The Deception Prototype Extractor maps high-dimensional data to understandable 'structural pattern units,' like 'profit manipulation' or 'asset inflation', making fraud signals transparent to auditors.
This balance of high recall and clear explanations makes FDPFormer an invaluable tool for intelligent auditing.
FDPFormer's advanced capabilities offer significant strategic advantages for financial regulation and corporate governance. Its ability to detect subtle, evolving fraud patterns in complex data structures minimizes regulatory risk and enhances investor confidence.
Strategic Benefits:
- Early Warning System: Proactive identification of financial deception, reducing the impact of fraudulent activities.
- Enhanced Regulatory Compliance: Provides regulators with a powerful tool to enforce standards and maintain market integrity.
- Improved Audit Efficiency: Automates initial risk assessment, allowing auditors to focus on high-risk areas identified by the model.
- Adaptability: While current training is static, the model's architecture is amenable to future enhancements for concept-drift monitoring and incremental learning, ensuring long-term relevance.
Integrating FDPFormer can transform financial oversight into a more data-driven, precise, and transparent process.

Uncovering Coordinated Fraud: Profit Inflation & Fictitious Assets
FDPFormer's unique axial attention mechanism excels at detecting complex fraud types that require coordination across multiple years and accounts. For instance, in cases of profit inflation or fictitious assets, traditional models struggle with the intricate web of cross-period inconsistencies. FDPFormer's ability to model both horizontal (within-year logic) and vertical (multi-year trends) relationships allows it to expose discrepancies like rapid revenue growth without matching cash flow or abnormal expansion of receivables, which are tell-tale signs of such schemes. Its prototypes learn to recognize these specific structural patterns, providing clear, auditable evidence.
Key Benefit: Improved detection of multi-year, multi-account coordinated fraud patterns.
| Method | Accuracy | Recall (1) | Precision (1) | AUC |
|---|---|---|---|---|
| w/o Axial Attention | 0.640 | 0.660 | 0.446 | 0.729 |
| w/o Prototype Learner | 0.645 | 0.670 | 0.452 | 0.734 |
