Decoupling Spatio-Temporal Prediction: When Lightweight Large Models Meet Adaptive Hypergraphs
STH-SepNet decouples temporal and spatial modeling for spatio-temporal prediction using a small LLM for time and a KNN-built adaptive hypergraph for space, and reports state-of-the-art MAE/RMSE on five traffic datasets.
