A Discrete-time Networked Competitive Bivirus SIS Model

no code implementations20 Oct 2023 Sebin Gracy, Ji Liu, Tamer Basar, Cesar A. Uribe

We identify a sufficient condition for exponential convergence to the disease-free equilibrium (DFE).

Competitive Networked Bivirus SIS spread over Hypergraphs

no code implementations25 Sep 2023 Sebin Gracy, Brian D. O. Anderson, Mengbin Ye, Cesar A. Uribe

The paper deals with the spread of two competing viruses over a network of population nodes, accounting for pairwise interactions and higher-order interactions (HOI) within and between the population nodes.

On the Endemic Behavior of a Competitive Tri-Virus SIS Networked Model

no code implementations23 Sep 2022 Sebin Gracy, Mengbin Ye, Brian DO Anderson, Cesar A. Uribe

This paper studies the endemic behavior of a multi-competitive networked susceptible-infected-susceptible (SIS) model.

Robust Distributed Optimization With Randomly Corrupted Gradients

no code implementations28 Jun 2021 Berkay Turan, Cesar A. Uribe, Hoi-To Wai, Mahnoosh Alizadeh

In this paper, we propose a first-order distributed optimization algorithm that is provably robust to Byzantine failures-arbitrary and potentially adversarial behavior, where all the participating agents are prone to failure.

A General Framework for Distributed Inference with Uncertain Models

no code implementations20 Nov 2020 James Z. Hare, Cesar A. Uribe, Lance Kaplan, Ali Jadbabaie

Non-Bayesian social learning theory provides a framework that solves this problem in an efficient manner by allowing the agents to sequentially communicate and update their beliefs for each hypothesis over the network.

Non-Bayesian Social Learning with Uncertain Models

no code implementations9 Sep 2019 James Z. Hare, Cesar A. Uribe, Lance Kaplan, Ali Jadbabaie

Non-Bayesian social learning theory provides a framework that models distributed inference for a group of agents interacting over a social network.

Accelerating Incremental Gradient Optimization with Curvature Information

1 code implementation31 May 2018 Hoi-To Wai, Wei Shi, Cesar A. Uribe, Angelia Nedich, Anna Scaglione

This paper studies an acceleration technique for incremental aggregated gradient ({\sf IAG}) method through the use of \emph{curvature} information for solving strongly convex finite sum optimization problems.
