WebApr 12, 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 ... 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:
WebThe preferred workflow for contributing to POT is to fork the main repository on GitHub, clone, and develop on a branch. Steps: Fork the project repository by clicking on the ‘Fork’ button near the top right of the page. This creates a copy of the code under your GitHub user account.
