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

Summary: Nuhuo: histogram imputation on road networks modeling regionality, proximity, sparsity and volatility via a global partition graph to capture regional/proximal correlations. Combines disentangled global/local encoders (GNN+RNN), two-layer attention fusion and a self-supervised autoencoder, outperforming SOTA in accuracy and robustness.
