The Non-Tightness of a Convex Relaxation to Rotation Recovery [PDF]
Sensors, 2021 We study the Perspective-n-Point (PNP) problem, which is fundamental in 3D vision, for the recovery of camera translation and rotation. A common solution applies polynomial sum-of-squares (SOS) relaxation techniques via semidefinite programming. Our main

On convex relaxation of graph isomorphism [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2015 Significance Graphs are a ubiquitous mathematical abstraction used in numerous problems in science and engineering. Of particular importance is the need to find the best structure-preserving matching of graphs. Since graph matching (GM) is a computationally intractable problem, numerous heuristics exist to approximate its solution. An

Computational and statistical tradeoffs via convex relaxation [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2013 Significance The growth in the size and scope of datasets in science and technology has created a need for foundational perspectives on data analysis that blend computer science and statistics. Specifically, the core challenge with massive datasets is that of guaranteeing improved accuracy of an analysis procedure as data accrue, even

Convex Relaxation Methods for Community Detection [PDF]
Statistical Science, 2021 This paper surveys recent theoretical advances in convex optimization approaches for community detection. We introduce some important theoretical techniques and results for establishing the consistency of convex community detection under various statistical models. In particular, we discuss the basic techniques based on the primal and dual analysis. We
