Spatial-Temporal Dynamic Graph Attention Networks for Ride-hailing Demand Prediction

no code implementations7 Jun 2020 Weiguo Pian, Yingbo Wu, Xiangmou Qu, Junpeng Cai, Ziyi Kou

However, existing GCN-based ride-hailing demand prediction methods only assign the same importance to different neighbor regions, and maintain a fixed graph structure with static spatial relationships throughout the timeline when extracting the irregular non-Euclidean spatial correlations.
