On the (almost) Global Exponential Convergence of the Overparameterized Policy Optimization for the LQR Problem
Moh Kamalul Wafi, Arthur Castello B. de Oliveira, Eduardo D. Sontag
In this work we study the convergence of gradient methods for nonconvex optimization problems -- specifically the effect of the problem formulation to the convergence behavior of t…
Regularizing Numerical Extremals Along Singular Arcs: A Lie-Theoretic Approach
Arthur Castello Branco de Oliveira, Milad Siami, Eduardo D. Sontag
Numerical ``direct'' approaches to time-optimal control often fail to find solutions that are singular in the sense of the Pontryagin Maximum Principle, performing better when sear…
On the ISS Property of the Gradient Flow for Single Hidden-Layer Neural Networks with Linear Activations
Arthur Castello B. de Oliveira, Milad Siami, Eduardo D. Sontag
Recent research in neural networks and machine learning suggests that using many more parameters than strictly required by the initial complexity of a regression problem can result…
