Meta Dynamic Graph for Traffic Flow Prediction

AAAI 2026technical

Traffic flow prediction is a typical spatio-temporal prediction problem and has a wide range of applications. The core challenge lies in modeling the underlying complex spatio-temporal dependencies. Various methods have been proposed, and recent studies show that the modeling of dynamics is useful t

Generative Human Trajectory Recovery via Embedding-Space Conditional Diffusion

ICML 2025poster

Recovering human trajectories from incomplete or missing data is crucial for many mobility-based urban applications, e.g., urban planning, transportation, and location-based services. Existing methods mainly rely on recurrent neural networks or attention mechanisms. Though promising, they encounter…

KITS: Inductive Spatio-Temporal Kriging with Increment Training Strategy

AAAI 2025technical

Sensors are commonly deployed to perceive the environment. However, due to the high cost, sensors are usually sparsely deployed. Kriging is the tailored task to infer the unobserved nodes (without sensors) using the observed nodes (with sensors). The essence of kriging task is transferability. Recen…

Towards Robust Trajectory Representations: Isolating Environmental Confounders with Causal Learning

IJCAI 2024poster

Trajectory modeling refers to characterizing human movement behavior, serving as a pivotal step in understanding mobility patterns. Nevertheless, existing studies typically ignore the confounding effects of geospatial context, leading to the acquisition of spurious correlations and limited generaliz…
