Convergence rates for regularized unbalanced optimal transport: the discrete case
Luca Nenna, Paul Pegon, Louis Tocquec
Unbalanced optimal transport (UOT) is a natural extension of optimal transport (OT) allowing comparison between measures of different masses. It arises naturally in machine learnin…
Grand-Canonical Optimal Transport
Simone Di Marino, Mathieu Lewin, Luca Nenna
We study a generalization of the multi-marginal optimal transport problem, which has no fixed number of marginals and is inspired of statistical mechanics. It consists in optim…
Convergence rate of entropy-regularized multi-marginal optimal transport costs
Luca Nenna, Paul Pegon
We investigate the convergence rate of multi-marginal optimal transport costs that are regularized with the Boltzmann-Shannon entropy, as the noise parameter tends to…
An ordinary differential equation for entropic optimal transport and its linearly constrained variants
Joshua Zoen-Git Hiew, Luca Nenna, Brendan Pass
We characterize the solution to the entropically regularized optimal transport problem by a well-posed ordinary differential equation (ODE). Our approach works for discrete margina…
