Data-Efficient and Robust Trajectory Generation through Pathlet Dictionary Learning

ArXi:2511.16105v2 Announce Type: replace Trajectory generation has recently drawn growing interest in privacy-preserving urban mobility studies and location-based service applications. Although many studies have used deep learning or generative AI methods to model trajectories and have achieved promising results, the robustness and interpretability of such models are largely unexplored. This limits the application of trajectory generation algorithms on noisy real-world data and their trustworthiness in downstream tasks.
