Spatio-temporal prediction technology is becoming increasingly important, not only focusing on the flow of traffic and people, but also covering multiple dimensions such as crime trends. However, traditional spatio-temporal prediction models are limited in accurate prediction due to insufficient urban data, and UrbanGPT emerges to fill this gap, and its strong generalization capability makes it show great potential in the field of zero-sample learning. Challenges faced by UrbanGPT include label scarcity and high training cost, as well as limitations of spatio-temporal prediction models in zero-sample generalization. However, by integrating a spatio-temporal dependent encoder and an instruction fine-tuning method, UrbanGPT successfully overcomes the challenges of zero-sample learning.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[146],"tags":[2902,216,1480,234],"collection":[],"class_list":["post-12065","post","type-post","status-publish","format-standard","hentry","category-news","tag-urbangpt","tag-216","tag-1480","tag-234"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/posts\/12065","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/comments?post=12065"}],"version-history":[{"count":0,"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/posts\/12065\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/media?parent=12065"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/categories?post=12065"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/tags?post=12065"},{"taxonomy":"collection","embeddable":true,"href":"https:\/\/www.1ai.net\/en\/wp-json\/wp\/v2\/collection?post=12065"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
