Variational Optimization for the Submodular Maximum Coverage Problem
Jian Du, Zhigang Hua, Shuang Yang
We examine the \emph{submodular maximum coverage problem} (SMCP), which is related to a wide range of applications. We provide the first variational approximation for this problem…
Distributed Frequency Offsets Estimation
Jian Du, Shaodan Ma
In this paper, we provide a distributed frequency offset estimation algorithm based on a variant of belief propagation (BP). Each agent in the network pre-compensates its carrier f…
Convergence Analysis of Belief Propagation on Gaussian Graphical Models
Jian Du, Shaodan Ma, Yik-Chung Wu +2
Gaussian belief propagation (GBP) is a recursive computation method that is widely used in inference for computing marginal distributions efficiently. Depending on how the factoriz…
Distributed Convergence Verification for Gaussian Belief Propagation
Jian Du, Soummya Kar, José M. F. Moura
Gaussian belief propagation (BP) is a computationally efficient method to approximate the marginal distribution and has been widely used for inference with high dimensional data as…
Convergence analysis of belief propagation for pairwise linear Gaussian models
Jian Du, Shaodan Ma, Yik-Chung Wu +2
Gaussian belief propagation (BP) has been widely used for distributed inference in large-scale networks such as the smart grid, sensor networks, and social networks, where local me…
Network-Wide Distributed Carrier Frequency Offsets Estimation and Compensation
Jian Du, Yik-Chung Wu
In this paper, we propose a fully distributed algorithm for frequency offsets estimation in decentralized systems. With the proposed algorithm, each node estimates its frequency of…
