Optimal transport in systems and control

Y Chen, TT Georgiou, M Pavon - Annual Review of Control …, 2021 - annualreviews.org
Optimal transport began as the problem of how to efficiently redistribute goods between
production and consumers and evolved into a far-reaching geometric variational framework …

Stochastic control liaisons: Richard sinkhorn meets gaspard monge on a schrodinger bridge

Y Chen, TT Georgiou, M Pavon - Siam Review, 2021 - SIAM
In 1931--1932, Erwin Schrödinger studied a hot gas Gedankenexperiment (an instance of
large deviations of the empirical distribution). Schrödinger's problem represents an early …

On the relation between optimal transport and Schrödinger bridges: A stochastic control viewpoint

Y Chen, TT Georgiou, M Pavon - Journal of Optimization Theory and …, 2016 - Springer
We take a new look at the relation between the optimal transport problem and the
Schrödinger bridge problem from a stochastic control perspective. Our aim is to highlight …

Optimal transport for Gaussian mixture models

Y Chen, TT Georgiou, A Tannenbaum - IEEE Access, 2018 - ieeexplore.ieee.org
We introduce an optimal mass transport framework on the space of Gaussian mixture
models. These models are widely used in statistical inference. Specifically, we treat the …

Multi-marginal optimal transport and probabilistic graphical models

I Haasler, R Singh, Q Zhang… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
We study multi-marginal optimal transport problems from a probabilistic graphical model
perspective. We point out an elegant connection between the two when the underlying cost …

Multi-marginal optimal transport using partial information with applications in robust localization and sensor fusion

F Elvander, I Haasler, A Jakobsson, J Karlsson - Signal Processing, 2020 - Elsevier
During recent decades, there has been a substantial development in optimal mass transport

Entropic and displacement interpolation: a computational approach using the Hilbert metric

Y Chen, T Georgiou, M Pavon - SIAM Journal on Applied Mathematics, 2016 - SIAM
Monge--Kantorovich optimal mass transport (OMT) provides a blueprint for geometries in the
space of positive densities---it quantifies the cost of transporting a mass distribution into …

Wasserstein proximal algorithms for the Schrödinger bridge problem: Density control with nonlinear drift

KF Caluya, A Halder - IEEE Transactions on Automatic Control, 2021 - ieeexplore.ieee.org
In this article, we study the Schrödinger bridge problem (SBP) with nonlinear prior dynamics.
In control-theoretic language, this is a problem of minimum effort steering of a given joint …
