Consensus-based Networked Tracking in Presence of Heterogeneous Time-Delays
Mohammadreza Doostmohammadian, Mohammad Pirani, Usman A. Khan
We propose a distributed (single) target tracking scheme based on networked estimation and consensus algorithms over static sensor networks. The tracking part is based on linear ti…
Distributed Constraint-Coupled Optimization over Lossy Networks
Mohammadreza Doostmohammadian, Usman A. Khan, Alireza Aghasi +1
This paper considers distributed resource allocation and sum-preserving constrained optimization over lossy networks, where the links are unreliable and subject to packet drops. We…
Variance reduced stochastic optimization over directed graphs with row and column stochastic weights
Muhammad I. Qureshi, Ran Xin, Soummya Kar +1
This paper proposes AB-SAGA, a first-order distributed stochastic optimization method to minimize a finite-sum of smooth and strongly convex functions distributed over an arbitrary…
Distributed saddle point problems for strongly concave-convex functions
Muhammad I. Qureshi, Usman A. Khan
In this paper, we propose GT-GDA, a distributed optimization method to solve saddle point problems of the form: $\min_{\mathbf{x}} \max_{\mathbf{y}} \{F(\mathbf{x},\mathbf{y}) :=G(…
A Stochastic Proximal Gradient Framework for Decentralized Non-Convex Composite Optimization: Topology-Independent Sample Complexity and Communication Efficiency
Ran Xin, Subhro Das, Usman A. Khan +1
Decentralized optimization is a promising parallel computation paradigm for large-scale data analytics and machine learning problems defined over a network of nodes. This paper is…
Distributed Detection and Mitigation of Biasing Attacks over Multi-Agent Networks
Mohammadreza Doostmohammadian, Houman Zarrabi, Hamid R. Rabiee +2
This paper proposes a distributed attack detection and mitigation technique based on distributed estimation over a multi-agent network, where the agents take partial system measure…
