Nuhuo: An Effective Estimation Model for Traffic Speed Histogram Imputation on A Road Network

Summary: Nuhuo imputes missing road-link speed histograms by modeling regional, proximal, sparse, and volatile spatio-temporal dependencies. A global partition graph, disentangled global/local GNN-RNN encoders, attention fusion, and autoencoder self-supervision deliver robust state-of-the-art accuracy.
