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…

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…

Uniform large-scale $ε$ -regularity for entropic optimal transport

Rishabh S. Gvalani, Lukas Koch

We study the regularity properties of the minimisers of entropic optimal transport providing a natural analogue of the $ε$ -regularity theory of quadratic optimal transpor…
