DeepDPM: Dynamic Population Mapping via Deep Neural Network

no code implementations25 Oct 2018 Zefang Zong, Jie Feng, Kechun Liu, Hongzhi Shi, Yong Li

In this paper, we first propose the idea to generate dynamic population distributions in full-time series, then we design dynamic population mapping via deep neural network(DeepDPM), a model that describes both spatial and temporal patterns using coarse data and point of interest information.
