On the Performance of Gradient Tracking with Local Updates

Edward Duc Hien Nguyen, Sulaiman A. Alghunaim, Kun Yuan +1

We study the decentralized optimization problem where a network of agents seeks to minimize the average of a set of heterogeneous non-convex cost functions distributedly. State…

A State Feedback Controller for Mitigation of Continuous-Time Networked SIS Epidemics

Yuan Wang, Sebin Gracy, César A. Uribe +2

The paper considers continuous-time networked susceptible-infected-susceptible (SIS) diseases spreading over a population. Each agent represents a sub-population and has its own he…

Unbounded Gradients in Federated Learning with Buffered Asynchronous Aggregation

Mohammad Taha Toghani, César A. Uribe

Synchronous updates may compromise the efficiency of cross-device federated learning once the number of active clients increases. The \textit{FedBuff} algorithm (Nguyen et al., 202…

On Arbitrary Compression for Decentralized Consensus and Stochastic Optimization over Directed Networks

Mohammad Taha Toghani, César A. Uribe

We study the decentralized consensus and stochastic optimization problems with compressed communications over static directed graphs. We propose an iterative gradient-based algorit…

On Acceleration of Gradient-Based Empirical Risk Minimization using Local Polynomial Regression

Ekaterina Trimbach, Edward Duc Hien Nguyen, César A. Uribe

We study the acceleration of the Local Polynomial Interpolation-based Gradient Descent method (LPI-GD) recently proposed for the approximate solution of empirical risk minimization…

On Distributed Exact Sparse Linear Regression over Networks

Tu Anh-Nguyen, César A. Uribe

In this work, we propose an algorithm for solving exact sparse linear regression problems over a network in a distributed manner. Particularly, we consider the problem where data i…
