Considersolving a system ofNstochastic differential equations interacting through a random matrixwith independent (not necessarily identically distributed) random coefficients. We show that the trajectories of averaged observables of, initialized from someindependent of, are universal, i.e., only depend on the choice of the distributionthrough its first and second moments (assuming e.g., sub-exponential tails). We take a general combinatorial approach to proving universality for dynamical systems with random coefficients, combining a stochastic Taylor expansion with a moment matching-type argument. Concrete settings for which our results imply universality include aging in the spherical SK spin glass, and Langevin dynamics and gradient flows for symmetric and asymmetric Hopfield networks.
