Convergence of a class of gradient-free optimisation schemes when the objective function is noisy, irregular, or both
Christophe Andrieu, Nicolas Chopin, Ettore Fincato +1
We investigate the convergence properties of a class of iterative algorithms designed to minimize a potentially non-smooth and noisy objective function, which may be algebraically…

Gradient-free optimization via integration
Christophe Andrieu, Nicolas Chopin, Ettore Fincato +1
We develop and analyse an approach to optimize functions not assumed to be convex, differentiable or even continuous. The algorithm be…
