Optimal and Practical Algorithms for Smooth and Strongly Convex Decentralized Optimization

Dmitry Kovalev, Adil Salim, Peter Richtárik

We consider the task of decentralized minimization of the sum of smooth strongly convex functions stored across the nodes of a network. For this problem, lower bounds on the number…

A Non-Asymptotic Analysis for Stein Variational Gradient Descent

Anna Korba, Adil Salim, Michael Arbel +2

We study the Stein Variational Gradient Descent (SVGD) algorithm, which optimises a set of particles to approximate a target probability distribution on $\mathbb{…

Primal Dual Interpretation of the Proximal Stochastic Gradient Langevin Algorithm

Adil Salim, Peter Richtárik

We consider the task of sampling with respect to a log concave probability distribution. The potential of the target distribution is assumed to be composite, \textit{i.e.}, written…

Distributed Fixed Point Methods with Compressed Iterates

Sélim Chraibi, Ahmed Khaled, Dmitry Kovalev +3

We propose basic and natural assumptions under which iterative optimization methods with compressed iterates can be analyzed. This problem is motivated by the practice of federated…

Maximum Mean Discrepancy Gradient Flow

Michael Arbel, Anna Korba, Adil Salim +1

We construct a Wasserstein gradient flow of the maximum mean discrepancy (MMD) and study its convergence properties. The MMD is an integral probability metric defined for a reprodu…

Stochastic Proximal Langevin Algorithm: Potential Splitting and Nonasymptotic Rates

Adil Salim, Dmitry Kovalev, Peter Richtárik

We propose a new algorithm---Stochastic Proximal Langevin Algorithm (SPLA)---for sampling from a log concave distribution. Our method is a generalization of the Langevin algorithm…
