WebApr 9, 2024 · Attention temporal graph convolutional network (A3T-GCN) : the A3T-GCN model explores the impact of a different attention mechanism (soft attention model) on traffic forecasts. Without an attention mechanism, the T-GCN model forecast short-term and long-term traffic forecasts better than the HA, GCN, and GRU models. WebTo tackle these challenges, we propose the Disentangled Intervention-based Dynamic graph Attention networks (DIDA). Our proposed method can effectively handle spatio-temporal distribution shifts in dynamic graphs by discovering and fully utilizing invariant spatio-temporal patterns. Specifically, we first propose a disentangled spatio-temporal ...
