Asymptotics of Wide Networks from Feynman Diagrams

Dyer, Ethan, Gur-Ari, Guy

Understand

Understanding the asymptotic behavior of wide networks is of considerable interest.

  • In this work, we present a general method for analyzing this large width behavior.
  • The method is an adaptation of Feynman diagrams, a standard tool for computing multivariate Gaussian integrals.
  • We apply our method to study training dynamics, improving existing bounds and deriving new results on wide network evolution during stochastic gradient descent.
