Global regularity and sparsity for regularised optimal transport

Xiaopeng Cheng, Lukas Koch, Haotian Xiao

We study regularised optimal transport with subquadratic or entropic regularisation. Under -assumptions on the marginals and the domains of their support, we prove global…

Sparsity and uniform regularity for regularised optimal transport

Rishabh S. Gvalani, Lukas Koch

We consider regularised quadratic optimal transport with subquadratic polynomial or entropic regularisation. In both cases, we prove interior Lipschitz-estimates on a transport-lik…

Plotting correlated data

Lukas Koch

A very common task in data visualization is to plot many data points with some measured y-value as a function of fixed x-values. Uncertainties on the y-values are typically present…
