The Monge optimal transport barycenter problem
Andrew D. Lipnick, Esteban G. Tabak, Giulio Trigila +3
A novel methodology is developed for the solution of the data-driven Monge optimal transport barycenter problem, where the pushforward condition is formulated in terms of the stati…

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…

Data-driven continuation of patterns and their bifurcations
Wenjun Zhao, Samuel Maffa, Björn Sandstede
Patterns and nonlinear waves, such as spots, stripes, and rotating spirals, arise prominently in many natural processes and in reaction-diffusion models. Our goal is to compute bou…
