Artificial Intelligence-Driven Multimodal Sensor Fusion for Complex Market Systems via Federated Transformer-Based Learning

This research introduces the Federated Market-Sensor Transformer (FMST), a novel framework addressing the challenges of integrating heterogeneous market data (price, order book, news, macroeconomic indicators) for predictive modeling. Traditional methods struggle with data complexity, temporal scale differences, and privacy concerns in distributed trading systems. FMST unifies data as multimodal time series, uses a cross-modal Transformer for dynamic interaction modeling, and employs federated learning for collaborative optimization without raw data sharing, enhancing cross-region generalization and privacy. Experimental results on a real-world dataset demonstrate FMST's superior performance over baselines in prediction accuracy and robustness, achieving an RMSE of 0.1136 and direction prediction accuracy of 74.56%.

FMST maintains strong performance under cross-region market environments due to adversarial alignment and similarity distillation, addressing non-IID challenges.

Ensuring Data Privacy Across Regions

In a competitive market environment, data privacy is paramount. Traditional centralized models require sharing raw data, which is often infeasible due to regulatory and confidentiality concerns. FMST's federated learning approach allows multiple regional nodes (e.g., exchanges, financial institutions) to collaboratively train a global model without exchanging any raw data. Instead, only model parameters or gradients are shared, which are then aggregated by a central server. This mechanism ensures that sensitive transactional and order book data remain localized, significantly enhancing security and compliance. The adversarial alignment and similarity distillation further mitigate non-IID issues, ensuring that regional biases do not compromise the global model's performance while maintaining strict data isolation.
