Asymptotic stability of stochastic LTV systems with applications to distributed dynamic fusion
Sam Safavi, Usman A. Khan
In this paper, we investigate asymptotic stability of linear time-varying systems with (sub-) stochastic system matrices. Motivated by distributed dynamic fusion over networks of m…
Measurement partitioning and observational equivalence in state estimation
Mohammadreza Doostmohammadian, Usman A. Khan
This letter studies measurement partitioning and equivalence in state estimation based on graph-theoretic principles. We show that a set of critical measurements (required to ensur…
Distributed Mirror Descent over Directed Graphs
Chenguang Xi, Qiong Wu, Usman A. Khan
In this paper, we propose Distributed Mirror Descent (DMD) algorithm for constrained convex optimization problems on a (strongly-)connected multi-agent network. We assume that each…
Graphic-theoretic distributed inference in social networks
Mohammadreza Doostmohammadian, Usman A. Khan
We consider distributed inference in social networks where a phenomenon of interest evolves over a given social interaction graph, referred to as the \emph{social digraph}. For inf…
