Sandwich Slice: Optimal Transport Potentials Are Optimal Generalized Slicers

Rocio Diaz Martin, Xinran Liu, Matthew Thorpe +1

Sliced optimal transport replaces a transport problem in Rd by one-dimensional problems along scalar slices, and has been used both to lower bound the Wasserstein distance W1 (max-…

Reduced Order Modeling of One-Dimensional Conservative PDEs via the Cumulative Distribution Transform

Harbir Antil, Rocío Díaz Martín, Ivan V. Medri +4

We propose a reduced order modeling (ROM) framework for 1D conservative PDEs based on the cumulative distribution transform (CDT). The CDT maps nonnegative, equal-mass states into…
