Question about GCN in ST_Enc.

Hello, I read your wonderful paper but still have some question.
It seemes that the GCN is always unable in ST_Enc, does it conflict with the statement "spatio-temporal encoder is designed to be independent of graph structures when modeling spatial correlations" in the paper? Or there is any misunderstanding I made?
Thanks!

Hello, thank you for your interest in our work. In many real-world scenarios, the graph structure is unknown; therefore, the designed spatio-temporal encoder does not rely on graph structures. We model spatial correlations using prompt instructions that contain spatial information, such as POIs.
