Complexity and performance for two classes of noise-tolerant first-order algorithms
S. Gratton, S. Jerad, Ph. L. Toint
Two classes of algorithms for optimization in the presence of noise are presented, that do not require the evaluation of the objective function. The first generalizes the well-know…

Hölder Gradient Descent and Adaptive Regularization Methods in Banach Spaces for First-Order Points
Serge Gratton, Sadok Jerad, Philippe L. Toint
This paper considers optimization of smooth nonconvex functionals in smooth infinite dimensional spaces. A Hölder gradient descent algorithm is first proposed for finding approxima…
