Hierarchical Attention Network with Correction for Cross-Domain User Association

AAAI 2026technical

Despite the rich spatiotemporal patterns contained in trajectory data from multiple Location-Based Social Network (LBSN) platforms, heterogeneous formats, semantic inconsistencies, and unequal user scales across platforms create substantial barriers to reliable identity mapping. Furthermore, GPS dri

Filling the Missings: Spatiotemporal Data Imputation by Conditional Diffusion

IJCAI 2025

Missing data in spatiotemporal systems presents a significant challenge for modern applications, ranging from environmental monitoring to urban traffic management. The integrity of spatiotemporal data often deteriorates due to hardware malfunctions and software failures in real-world deployments. Cu
