Accelerated Stochastic Zeroth-Order Quasar-Convex Optimization

Eméric Gbaguidi, Julien Hermant

We consider unconstrained minimization of smooth quasar-convex functions when only noisy function evaluations are accessible through a stochastic zeroth-order oracle. For these non…

Acceleration for Polyak-Łojasiewicz Functions with a Gradient Aiming Condition

Julien Hermant

It is known that when minimizing smooth Polyak-Łojasiewicz (PL) functions, momentum algorithms cannot significantly improve the convergence bound of gradient descent, contrasting w…

Continuized Nesterov Momentum Achieves the O(ε−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 ε-approximation of a stat…

Continuized Nesterov Acceleration for Non-Convex Optimization

Julien Hermant, Jean-François Aujol, Charles Dossal +2

In convex optimization, continuous-time counterparts have been a fruitful tool for analyzing momentum algorithms. Fewer such examples are available when the function to minimize is…
