Before revision:  Specifically, the first is node features, we design a efficient-spectral-clustering  with anchors (ESC-ANCH) approach to efficiently aggregate feature representationsfrom all similar nodes , no matter how far away they are.
After revision:  Specifically, the first is node features, we design a efficient-spectral-clustering (ESC) and an ESC with anchors (ESC-ANCH) approach to efficiently aggregate feature representationsfrom all similar nodes , no matter how far away they are.
