Comprehensive numerical evaluations on four real-world datasets reveal that the proposed methods achieve state-of-the-art performance and significantly outperform the benchmarks.<\/jats:p>","DOI":"10.24963\/ijcai.2022\/545","type":"proceedings-article","created":{"date-parts":[[2022,7,15]],"date-time":"2022-07-15T22:55:56Z","timestamp":1657925756000},"page":"3926-3932","source":"Crossref","is-referenced-by-count":48,"title":["FOGS: First-Order Gradient Supervision with Learning-based Graph for Traffic Flow Forecasting"],"prefix":"10.24963","author":[{"given":"Xuan","family":"Rao","sequence":"first","affiliation":[{"name":"University of Electronic Science and Technology of China"}]},{"given":"Hao","family":"Wang","sequence":"additional","affiliation":[{"name":"Wuhan University, China"}]},{"given":"Liang","family":"Zhang","sequence":"additional","affiliation":[{"name":"KAUST"}]},{"given":"Jing","family":"Li","sequence":"additional","affiliation":[{"name":"Inception Institute of Artificial Intelligence"}]},{"given":"Shuo","family":"Shang","sequence":"additional","affiliation":[{"name":"University of Electronic Science and Technology of China"}]},{"given":"Peng","family":"Han","sequence":"additional","affiliation":[{"name":"Aalborg University, Denmark"}]}],"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":"2022-07-18T07:10:18Z","timestamp":1658128218000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2022\/545"}},"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\/545","relation":{},"subject":[],"published":{"date-parts":[[2022,7]]}}}
