A Proximal Method for Composite Optimization with Smooth and Convex Components

Samet Uzun, Dayou Luo, Behçet Açıkmeşe +1

We introduce prox-convex for minimizing $F (x) = g (x) + h (C (x)) + s (R (x))$ , where $g$ and $h$ are convex, $C$ and $s$ are smooth, and each component of $R$ 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…
