Entropic Optimal Transport: Geometry and Large Deviations

WebOptimal transport is a powerful mathematical theory at the interface between optimization and probability theory with far reaching applications. It defines a natural tool to study probability distributions in the many situations where they appear: data science, partial differential equations, statistics or shape processing. WebSep 24, 2024 · Optimal transport gives us a way to quantify the similarity between two probability density functions in terms of the lowest total cost incurred by completely shoveling one pile into the shape and location of the other. Formally, the general optimal transport problem between two probability distributions and over a space is defined as:
