no code implementations6 Feb 2024 Kethmi Hirushini Hettige, Jiahao Ji, Shili Xiang, Cheng Long, Gao Cong, Jingyuan Wang

Air quality prediction and modelling plays a pivotal role in public health and environment management, for individuals and authorities to make informed decisions.

Self-Supervised Deconfounding Against Spatio-Temporal Shifts: Theory and Modeling

1 code implementation21 Nov 2023 Jiahao Ji, Wentao Zhang, Jingyuan Wang, Yue He, Chao Huang

It first encodes traffic data into two disentangled representations for associating invariant and variant ST contexts.

Multi-Factor Spatio-Temporal Prediction based on Graph Decomposition Learning

no code implementations16 Oct 2023 Jiahao Ji, Jingyuan Wang, Yu Mou, Cheng Long

The framework consists of two main components: an automatic graph decomposition module that decomposes the original graph structure inherent in ST data into subgraphs corresponding to different factors, and a decomposed learning network that learns the partial ST data on each subgraph separately and integrates them for the final prediction.

Spatio-Temporal Self-Supervised Learning for Traffic Flow Prediction

1 code implementation7 Dec 2022 Jiahao Ji, Jingyuan Wang, Chao Huang, Junjie Wu, Boren Xu, Zhenhe Wu, Junbo Zhang, Yu Zheng

ii) These models fail to capture the temporal heterogeneity induced by time-varying traffic patterns, as they typically model temporal correlations with a shared parameterized space for all time periods.
