Recovering low-rank structures via eigenvector perturbation analysis is a common problem
in statistical machine learning, such as in factor analysis, community detection, ranking …

Many important geometric estimation problems naturally take the form of synchronization
over the special Euclidean group: estimate the values of a set of unknown group elements x …

Cyber-physical systems (CPSs) are the next generation of engineered systems in which
computing, communication, and control technologies are tightly integrated. Research on …

Clock synchronization is a critical component in the operation of wireless sensor networks
(WSNs), as it provides a common time frame to different nodes. It supports functions such as …

This paper describes a new consensus-based protocol, referred to as Average TimeSync
(ATS), for synchronizing the clocks of a wireless sensor network. This algorithm is based on …

We study the distributed averaging problem on arbitrary connected graphs, with the
additional constraint that the value at each node is an integer. This discretized distributed …

This paper considers time synchronization in wireless sensor networks. When the
communication delay is negligible, the maximum time synchronization (MTS) protocol is …

The angular synchronization problem is to obtain an accurate estimation (up to a constant
additive phase) for a set of unknown angles θ1,…, θn from m noisy measurements of their …

We estimate n phases (angles) from noisy pairwise relative phase measurements. The task
is modeled as a nonconvex least-squares optimization problem. It was recently shown that …

The problem of estimating the phases (angles) of a complex unit-modulus vector z from their
noisy pairwise relative measurements C=zz^*+σW, where W is a complex-valued Gaussian …
