Recent Scalability Improvements for Semidefinite Programming With Applications in Machine Learning, Control, and Robotics

Journal Article
Historically, scalability has been a major challenge for the successful application of semidefinite programming in fields such as machine learning, control, and robotics. In this article, the authors survey recent approaches to this challenge, including those that exploit structure (e.g., sparsity and symmetry) in a problem, those that produce low-rank approximate solutions to semidefinite programs, those that use more scalable algorithms that rely on augmented Lagrangian techniques and the alternating-direction method of multipliers, and those that trade off scalability with conservatism (e.g., by approximating semidefinite programs with linear and second-order cone programs). For each class of approaches, the authors provide a high-level exposition, an entry point to the corresponding literature, and examples drawn from machine learning, control, or robotics. The authors also present a list of software packages that implement many of the techniques discussed in the review. The authors' hope is that this article will serve as a gateway to the rich and exciting literature on scalable semidefinite programming for both theorists and practitioners.
