PILOT-C: Physics-Informed Low-Distortion Optimal Trajectory Compression
Kefei Wu, Baihua Zheng, Weiwei Sun
Location-aware devices continuously generate massive volumes of trajectory data, creating demand for efficient compression. Line simplification is a common solution but typically a…
RNTrajRec: Road Network Enhanced Trajectory Recovery with Spatial-Temporal Transformer
Yuqi Chen, Hanyuan Zhang, Weiwei Sun +1
GPS trajectories are the essential foundations for many trajectory-based applications, such as travel time estimation, traffic prediction and trajectory similarity measurement. Mos…
Adaptive Structural Similarity Preserving for Unsupervised Cross Modal Hashing
Liang Li, Baihua Zheng, Weiwei Sun
Cross-modal hashing is an important approach for multimodal data management and application. Existing unsupervised cross-modal hashing algorithms mainly rely on data features in pr…
Multi-Agent Reinforcement Learning for Traffic Signal Control through Universal Communication Method
Qize Jiang, Minhao Qin, Shengmin Shi +2
How to coordinate the communication among intersections effectively in real complex traffic scenarios with multi-intersection is challenging. Existing approaches only enable the co…
