Powell-Style Model-Based Derivative-Free Optimization with Complexity Guarantees
Abraar Chaudhry, Katya Scheinberg, Scholar Sun
We propose variants of model-based trust region derivative-free algorithms that are closest to methods initially proposed and implemented by Powell. These methods rely on low degre…
Generalized Ellipsoids
Amir Ali Ahmadi, Abraar Chaudhry, Cemil Dibek
We introduce a family of symmetric convex bodies called generalized ellipsoids of degree (GE-s), with ellipsoids corresponding to the case of . Generalized ellipsoids (…
Safely Learning Dynamical Systems from Short Trajectories
Amir Ali Ahmadi, Abraar Chaudhry, Vikas Sindhwani +1
A fundamental challenge in learning to control an unknown dynamical system is to reduce model uncertainty by making measurements while maintaining safety. In this work, we formulat…
