Wasserstein Contraction Bounds on Closed Convex Domains with Applications to Stochastic Adaptive Control
Tyler Lekang, Andrew Lamperski
This paper is motivated by the problem of quantitatively bounding the convergence of adaptive control methods for stochastic systems to a stationary distribution. Such bounds are u…
