Convolutions on the Spatio-Temporal Graph

[spidercatfly]

Hi, team! Thanks for your excellent work, although it is not open source.

I have a question about the “Convolutions on the Spatio-Temporal Graph” stage: The message passing through $G^{time}$ only makes sense when it connects $G^{space}$ through $G^{time}$ and then back to $G^{space}$. Message passing solely within $G^{time}$, or between different $G^{time}$ matrices, doesn’t seem to have any meaningful purpose.

Can someone answer this question? Thanks for your help!
