DSFNet: Learning Dual-Domain Spectral Operators for Multi-Modality Spatio-Temporal Forecasting in Urban Transportation Systems
TL;DR
Existing methods for Multi-Modality Spatio-Temporal Forecasting (MoSTF) struggle to accurately model the relationships between different traffic data types. DSFNet, a new framework, learns dual-domain spectral operators to better capture these complex interactions.
✦ Why It Matters
Engineers can leverage DSFNet to improve traffic forecasting accuracy in urban planning and management.
Key Takeaways
- Utilize DSFNet for accurate urban transportation forecasting.
- Incorporate diverse traffic modalities in your models.
- Leverage dual-domain spectral filtering for better spatial modeling.
- Apply external gating mechanisms to manage temporal dynamics.
How It Works
DSFNet employs dual-domain spectral filtering to effectively capture heterogeneous spatial patterns and model relationships between different traffic modalities. By factorizing interactions into feature-domain and spatial-domain spectral operators, it allows for scalable modeling of complex dependencies, enhancing the overall forecasting accuracy.
