Continuized Nesterov Momentum Achieves the $O({\epsilon }^{-7/4})$ Complexity in Smooth Nonconvex Optimization

Julien Hermant, Jean-François Aujol, Charles Dossal +3

For first-order optimization of non-convex functions with Lipschitz-continuous gradient and Hessian, the best-known complexity for reaching an $\epsilon$-approximation of a stat…
