Efficient Learning of Distributed Linear-Quadratic Controllers
Salar Fattahi, Nikolai Matni, Somayeh Sojoudi
In this work, we propose a robust approach to design distributed controllers for unknown-but-sparse linear and time-invariant systems. By leveraging modern techniques in distribute…

On the Absence of Spurious Local Trajectories in Time-varying Nonconvex Optimization
S. Fattahi, C. Josz, Y. Ding +3
In this paper, we study the landscape of an online nonconvex optimization problem, for which the input data vary over time and the solution is a trajectory rather than a single poi…

Learning Sparse Dynamical Systems from a Single Sample Trajectory
Salar Fattahi, Nikolai Matni, Somayeh Sojoudi
This paper addresses the problem of identifying sparse linear time-invariant (LTI) systems from a single sample trajectory generated by the system dynamics. We introduce a Lasso-li…
