A Proximal Method for Composite Optimization with Smooth and Convex Components

Samet Uzun, Dayou Luo, Behçet Açıkmeşe +1

We introduce prox-convex for minimizing , where and are convex, and are smooth, and each component of is convex (possibly nonsmooth).…

Optimization Outperforms Unscented Techniques for Nonlinear Smoothing

Payton Howell, Aleksandr Aravkin

We review optimization-based approaches to smoothing nonlinear dynamical systems. These approaches leverage the fact that the Extended Kalman Filter and corresponding smoother can…

A Stochastic Record-Value Approach to Global Simulation Optimization

Rohan Rele, Zelda Zabinsky, Giulia Pedrielli +1

Black-box optimization is ubiquitous in machine learning, operations research and engineering simulation. Black-box optimization algorithms typically do not assume structural infor…

A Levenberg-Marquardt Method for Nonsmooth Regularized Least Squares

Aleksandr Y. Aravkin, Robert Baraldi, Dominique Orban

We develop a Levenberg-Marquardt method for minimizing the sum of a smooth nonlinear least-squar es term and a nonsmooth term . Both and $…

Theoretical Advances in Current Estimation and Navigation from a Glider-Based Acoustic Doppler Current Profiler (ADCP)

Jacob Stevens-Haas, Sarah E. Webster, Aleksandr Aravkin

We examine acoustic Doppler current profiler (ADCP) measurements from underwater gliders to determine glider position, glider velocity, and subsurface current. ADCPs, however, do n…

l1-Norm Minimization with Regula Falsi Type Root Finding Methods

Metin Vural, Aleksandr Y. Aravkin, Sławomir Stan'czak

Sparse level-set formulations allow practitioners to find the minimum 1-norm solution subject to likelihood constraints. Prior art requires this constraint to be convex. In this le…
