Convex Relaxations for Permutation Problems [PDF]
SIAM Journal on Matrix Analysis and Applications, 2015 Seriation seeks to reconstruct a linear order between variables using unsorted, pairwise similarity information. It has direct applications in archeology and shotgun gene sequencing for example. We write seriation as an optimization problem by proving the equivalence between the seriation and combinatorial 2-SUM problems on similarity matrices (2-SUM ...

Performance Analysis of Regularized Convex Relaxation for Complex-Valued Data Detection
Mathematics, 2022 In this work, we study complex-valued data detection performance in massive multiple-input multiple-output (MIMO) systems. We focus on the problem of recovering an n-dimensional signal whose entries are drawn from an arbitrary constellation K⊂C from m ...

Contamination estimation via convex relaxations [PDF]
2015 IEEE International Symposium on Information Theory (ISIT), 2015 Identifying anomalies and contamination in datasets is important in a wide variety of settings. In this paper, we describe a new technique for estimating contamination in large, discrete valued datasets. Our approach considers the normal condition of the data to be specified by a model consisting of a set of distributions.

A Gridmap-Path Reshaping Algorithm for Path Planning
IEEE Access, 2019 Path planning is a vital function of robotic systems. Different from existing roadmap algorithms which first determine the free space and then determine the collision-free path, researchers recently proposed several convex relaxation based smoothing ...
