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…
Learning Dynamical Systems with Side Information
Amir Ali Ahmadi, Bachir El Khadir
We present a mathematical and computational framework for the problem of learning a dynamical system from noisy observations of a few trajectories and subject to side information.…
Complexity aspects of local minima and related notions
Amir Ali Ahmadi, Jeffrey Zhang
We consider the notions of (i) critical points, (ii) second-order points, (iii) local minima, and (iv) strict local minima for multivariate polynomials. For each type of point, and…
On the complexity of finding a local minimizer of a quadratic function over a polytope
Amir Ali Ahmadi, Jeffrey Zhang
We show that unless P=NP, there cannot be a polynomial-time algorithm that finds a point within Euclidean distance (for any constant ) of a local minimizer of an …
