报告摘要
当前时空智能(SpaceTimeAI)和地理空间智能(GeoAI)已是热门的话题, 该研究领域旨在将计算机科学的最新方法(如深度学习)应用于地理空间问题。虽然深度学习方法因其对栅格数据的自然适用性而在图像处理中取得了巨大成功, 但仍未广泛应用于其他空间和时空数据类型。本演讲提出了使用基于网络(和图)的框架作为一般空间结构来表示通常由点、折线和多边形表示的时空过程的命题。我们举例说明了网络和基于图的SpaceTimeAI，从基于图的深度学习预测，到时空聚类和优化。这些应用展示了基于网络(图)的SpaceTimeAI在智慧城市应用中的优势，并介绍其在交通出行、警务和公共卫生等领域的应用。
Abstract
SpaceTimeAI and GeoAI are currently hot topics, applying the latest algorithms in computer science, such as deep learning, to spatiotemporal data. Although deep learning algorithms have been successfully applied to raster data due to their natural applicability to image processing, their applications in other spatial and space-time data types are still immature. This talk sets up the proposition of using a network (& graph)-based framework as a generic spatial structure to present space-time processes that are usually represented by the points, polylines, and polygons. We illustrate network and graph-based SpaceTimeAI, from graph-based deep learning for prediction, to space-time clustering and optimisation. These applications demonstrate the advantages of network (graph)-based SpaceTimeAI for smart cities applications including transport & mobility, crime & policing, and public health.
