Geometry and Convergence of Quadratically Regularized Optimal Transport II
Alberto González-Sanz, Marcel Nutz
We study quadratically regularized optimal transport with quadratic cost in the regime of small regularization , where the support of the optimal coupling is sparse. F…

Sharp Asymptotics for Regularized Optimal Transport
Carlos Cardoso-Perelló, Alberto González-Sanz, Marcel Nutz
We study the small-regularization limit for -regularized optimal transport with and for entropically regularized optimal transport (EOT). The exact first-order (r…
