Fast Trajectory Similarity Computation over Road networks

With the widespread application of trajectory data in areas such as traffic management and route planning, efficiently computing trajectory similarity for fast retrieval has become a critical challenge. Existing methods for trajectory similarity measurement often face issues of l...

Closed-Form and Boundary Expressions for Task-Success Probability in Status-Driven Systems

Status-driven task offloading appears in many systems such as vehicular coordination, UAV control, and compute-first networking, where an user-side node (or access point, AP) forwards user tasks based on periodically received server status. Whether a task ultimately succeeds depe...

Efficient Discovery of Motif Transition Process for Large-Scale Temporal Graphs

Understanding the dynamic transition of motifs in temporal graphs is essential for revealing how graph structures evolve over time, identifying critical patterns, and predicting future behaviors, yet existing methods often focus on predefined motifs, limiting their ability to com...
