STLGRU: Spatio-Temporal Lightweight Graph GRU for Traffic Flow Prediction

1 code implementation8 Dec 2022 Kishor Kumar Bhaumik, Fahim Faisal Niloy, Saif Mahmud, Simon Woo

Specifically, our proposed STLGRU can effectively capture dynamic local and global spatial-temporal relations of traffic networks using memory-augmented attention and gating mechanisms in a continuously synchronized manner.
