LSTF makes use of long-term dependency structure between the spatial and temporal domains, as well as the contextual information. Recent studies have revealed the potential of multi-graph neural networks (MGNNs) to improve prediction performance. However, existing MGNN methods do not work well when applied to LSTF due to several issues: the low level of generality, insufficient use of contextual information, and the imbalanced graph fusion approach. To address these issues, we construct new graph models to represent the contextual information of each node and exploit the long-term spatio-temporal data dependency structure. To aggregate the information across multiple graphs, we propose a new dynamic multi-graph fusion module to characterize the correlations of nodes within a graph and the nodes across graphs via the spatial attention and graph attention mechanisms. Furthermore, we introduce a trainable weight tensor to indicate the importance of each node in different graphs. Extensive experiments on two large-scale datasets demonstrate that our proposed approaches significantly improve the performance of existing graph neural network models in LSTF prediction tasks.<\/jats:p>","DOI":"10.24963\/ijcai.2022\/309","type":"proceedings-article","created":{"date-parts":[[2022,7,16]],"date-time":"2022-07-16T02:55:56Z","timestamp":1657940156000},"page":"2225-2232","source":"Crossref","is-referenced-by-count":54,"title":["Long-term Spatio-Temporal Forecasting via Dynamic Multiple-Graph Attention"],"prefix":"10.24963","author":[{"given":"Wei","family":"Shao","sequence":"first","affiliation":[{"name":"Arizona State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiling","family":"Jin","sequence":"additional","affiliation":[{"name":"Xidian University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuo","family":"Wang","sequence":"additional","affiliation":[{"name":"ETH Zurich"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yufan","family":"Kang","sequence":"additional","affiliation":[{"name":"RMIT University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Xiao","sequence":"additional","affiliation":[{"name":"Xidian University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamid","family":"Menouar","sequence":"additional","affiliation":[{"name":"Qatar Mobility Innovations Center, Qatar University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaofeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Arizona State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junshan","family":"Zhang","sequence":"additional","affiliation":[{"name":"University of California Davis"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Flora","family":"Salim","sequence":"additional","affiliation":[{"name":"University of New South Wales"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10584","event":{"name":"Thirty-First International Joint Conference on Artificial Intelligence {IJCAI-22}","theme":"Artificial Intelligence","location":"Vienna, Austria","acronym":"IJCAI-2022","number":"31","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2022,7,23]]},"end":{"date-parts":[[2022,7,29]]}},"container-title":["Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2022,7,18]],"date-time":"2022-07-18T11:08:58Z","timestamp":1658142538000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2022\/309"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2022,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2022\/309","relation":{},"subject":[],"published":{"date-parts":[[2022,7]]}}}
