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…
A Proximal Quasi-Newton Trust-Region Method for Nonsmooth Regularized Optimization
Aleksandr Y. Aravkin, Robert Baraldi, Dominique Orban
We develop a trust-region method for minimizing the sum of a smooth term and a nonsmooth term ), both of which can be nonconvex. Each iteration of our method minimizes a pos…
