Accelerated and Stable Convergence with Anchored Generalized Optimistic Method

Motahareh Sohrabi, Jianxin You, Simon Lacoste-Julien +2

We study first-order methods for solving monotone variational inequalities arising in min-max optimization. Classical approaches such as the extragradient method rely on two gradie…

On the Interaction of Batch Noise, Adaptivity, and Compression, under -Smoothness: An SDE Approach

Enea Monzio Compagnoni, Rustem Islamov, Frank Norbert Proske +3

Distributed stochastic optimization intertwines (i) stochastic gradient noise, (ii) communication compression, and (iii) adaptive/normalized updates. While each factor has been stu…

Heterogeneous-Horizon Exact-Weight Local SGD

Dmitry Pasechnyuk-Vilensky, Martin Takáč

We study adaptive aggregation for heterogeneous local SGD in convex finite-sum optimization, allowing heterogeneous local horizons, minibatch sizes, gradient noise, and participati…

On the Role of Batch Size in Stochastic Conditional Gradient Methods

Rustem Islamov, Roman Machacek, Aurelien Lucchi +3

We study the role of batch size in stochastic conditional gradient methods under a -Kurdyka-Łojasiewicz (-KL) condition. Focusing on momentum-based stochastic conditional…

Median Clipping for Zeroth-order Non-Smooth Convex Optimization and Multi-Armed Bandit Problem with Heavy-tailed Symmetric Noise

Nikita Kornilov, Yuriy Dorn, Aleksandr Lobanov +5

In this paper, we consider non-smooth convex optimization with a zeroth-order oracle corrupted by symmetric stochastic noise. Unlike the existing high-probability results requiring…
