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 … WebNov 23, 2024 · Python toolbox to compute and differentiate Optimal Transport (OT) distances. It computes the cost using (generalization of) Sinkhorn's algorithm [1], which can in turn be applied: To optimize barycenters and their weights [2]. To perform shape registration [9]. As a loss between machine learning features [1].
