Formally, the general optimal transport problem between two probability distributions and over a space is defined as:
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. 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].
WebOptimal transport. Optimal transport (OT) [33] is a natural type of divergence for registration problems because it accounts for the underlying geometry of the space. In Euclidean settings, OT gives rise to a metric known as the Wasserstein distance W(µ,⌫) which measures the minimum effort
