Optimal transport with a density-dependent cost function
Zichu Wang, Esteban G. Tabak
A new pairwise cost function is proposed for the optimal transport barycenter problem, adopting the form of the minimal action between two points, with a Lagrangian that takes into…

The hierarchical barycenter: conditional probability simulation with structured and unobserved covariates
Esteban G. Tabak, Giulio Trigila, Wenjun Zhao
This paper presents a new method for conditional probability density simulation. The method is design to work with unstructured data set when data are not characterized by the same…
