UrbanGPT

The University of Hong Kong and Baidu jointly released the first smart city big model UrbanGPT, which has triggered a major breakthrough in the field of spatiotemporal prediction technology. The importance of spatiotemporal prediction technology is becoming increasingly prominent, focusing not only on the flow of traffic and people, but also covering multiple dimensions such as crime trends. However, due to insufficient urban data, traditional spatiotemporal prediction models are limited in terms of accurate prediction. The emergence of UrbanGPT fills this gap, and its strong generalization ability makes it show great potential in the field of zero-shot learning. Challenges faced by UrbanGPT include scarce labels and high training costs…
