On the validity of kernel approximations for orthogonally-initialized neural networks

arXiv:2104.05878

Abstract

In this note we extend kernel function approximation results for neural networks with Gaussian-distributed weights to single-layer networks initialized using Haar-distributed random orthogonal matrices (with possible rescaling). This is accomplished using recent results from random matrix theory.
