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: WebDec 24, 2024 · I'm trying to code Sinkhorn algorithm, especially I'm trying to see if I can compute the optimal transportation between two measures when the strengh of the entropic regularization converges to 0. For exemple let's transport the uniform measure $U$ over $ [0;1]$ into the uniform measure $V$ over $ [1;2]$.

WebOptimal transport (OT) has been gaining in recent years an increasing attention in the machine learning community, mainly due to its capacity to exploit the geometric property of the samples. Generally speaking, OT is a mathematical tool to compare distributions by computing a transportation mass plan from a source to a target distribution. WebMar 1, 2024 · Optimal transport (OT) theory can be informally described using the words of the French mathematician Gaspard Monge (1746-1818): A worker with a shovel in hand has to move a large pile of sand lying on a construction site. The goal of the worker is to erect with all that sand a target pile with a prescribed shape (for example, that of a giant sand …
