[KDD 2019 Paper Applied Data Science Track] DeepUrbanEvent: A System for Predicting Citywide Crowd Dynamics at Big Events
Under the situations of big events, citywide crowd dynamics would manifest some different patterns from the normal routine. In this study, we propose a highly deployable system to extract the trend from momentary changes, and leverage multitask learning to predict crowd density and crowd flows simultaneously.
