With the rapid advances in new-generation information technologies such as the Internet of Things, 5G, and mobile Internet, Spatio-Temporal (ST) data are growing explosively in urban areas. In contrast to image, text, and voice data, ST data often present unique spatio-temporal characteristics, including spatial distance and hierarchy, as well as temporal closeness, periodicity, and trend. Spatio-Temporal AI is a proprietary AI technology for ST data, where AI meets conventional city-related fields, like transportation, civil engineering, environment, and economy, in the context of urban spaces. This talk first introduces the concept of Spatio- Temporal AI, discussing its general framework and key challenges from the perspective of computer science. Secondly, we classify the applications of spatio-temporal AI into four categories, consisting of modeling ST trajectories, ST grid data, ST graphs, and ST series. We also present representative scenarios in each category. Thirdly, we delineate our recent progress in the methodologies of the above four categories in various applications. Finally, we outlook on the future of spatio-temporal AI, suggesting a few research topics that are somehow missing in the community.
