CIWI-CKT: Chaos-Informed Wave Interference Feature Fusion and Cross-City Knowledge Transfer for Traffic Flow Forecasting

· Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Data Science & Analytics · Depth: Expert, quick

Summary

CIWI-CKT is a novel Chaos-Informed Wave Interference Feature Fusion framework with Cross-City Knowledge Transfer designed to improve traffic flow prediction, particularly in data-scarce, cross-city environments. It addresses the challenges posed by chaotic traffic dynamics, complex spatio-temporal dependencies, and diverse urban networks, which hinder generalization for existing deep learning models. The framework introduces three key innovations: chaos-informed wave generation, which extracts measurable chaos invariants and models traffic as adaptive wave components; meta-interference processing, which captures wave interactions between support and query regimes and provides a predictability score; and chaos-aware meta-learning, which facilitates efficient cross-city knowledge transfer while preserving chaotic characteristics. CIWI-CKT establishes theoretical guarantees for stability, dimension reduction, and generalization. Extensive experiments on four real-world traffic datasets demonstrate its significant outperformance over current spatio-temporal graph learning, transfer learning, prompt-based, and few-shot methods, enhancing prediction accuracy and substantially reducing required training data.

Key takeaway

For Machine Learning Engineers developing traffic prediction systems in data-scarce or cross-city environments, you should evaluate CIWI-CKT. Its novel chaos-informed wave interference and cross-city knowledge transfer mechanisms significantly improve accuracy and reduce training data requirements compared to existing methods. Consider integrating its principles to enhance model generalization and robustness when facing complex, chaotic traffic dynamics across heterogeneous urban networks.
