Exploring Oversmoothing with Householder Matrices
This work proves three core properties of HouseGNN: every internal layer preserves the node-wise Euclidean norm; the Householder reflector is scale scale and sign-invariant in the message; and pairwise distance between nodes can change through mismatch between node-wise orthogonal operators.
