Beyond Sequences: A Dynamic Hierarchical Heterogeneous Spatio-Temporal Graph for Irregular Multivariate Time Series Forecasting

Xiaowei Yan, Zhuo Li, Junjie Zhang, Bing Li, Jun Yan, Buzhou Tang

IJCAI 2026

Irregular Multivariate Time Series (IMTS) analysis is a challenging task as asynchronous irregular sampling disrupts intra-variable temporal consistency and cross-variable alignment. Most existing methods model multivariate correlations at either the variable or observation level in static ways. The

Receptive Field Pyramid Network for Object Detection

Faming Wu, Andy J. Ma, Yangshan Pan, Yuan Gao, Xiaowei Yan

ICASSP 2020accepted

Current state-of-the-art methods usually utilize feature pyramid to provide various receptive fields for detecting objects at different scales. However, the feature maps from low- to high-level layers have large semantic gaps and are with different spatial resolutions, so that their representational…
