Distributed Matrix Completion: Application to Cooperative Positioning in Noisy Environments
Abstract
The PI and collaborators developed novel algorithms for positioning, building on earlier developments in matrix completion and high-dimensional statistics. In particular, a distributed version of matrix completion-based positioning, and a gossip version of low-rank approximation were developed. A convex relaxation for positioning in the presence of noise was shown to be constant-optimal. Additional contributions were made in several other areas: Finding dense substructures of large networks in nearly linear time; Approximate message passing algorithms and in particular their application to spatially-coupled compressed sensing; Measures of statistical significance in high dimension.
