Rooted Motif Positional Encoding
Augment every graph node with a vector of rooted walk and motif densities rather than relying only on degree or Laplacian positional encodings. This should distinguish nodes or communities with identical expected degree but different connectivity profiles, especially in equal-degree stochastic block models and graphs with locally heterogeneous structure.
