New mathematical distances for partial optimal transport unveiled

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced new mathematical tools, entropic partial optimal transport and a partial mixture Gromov--Wasserstein distance, designed to compare probability measures and metric measure spaces. These methods address limitations of existing balanced formulations by allowing for partial matching, which is beneficial for datasets with outliers or incomplete information. The paper details the mathematical properties of these new distances, including their existence, uniqueness, and limits, and demonstrates their application through numerical experiments on synthetic data and point clouds.

    Entropic Partial Optimal Transport and Partial Gromov--Wasserstein Distance between Gaussian Mixtures

    arXiv:2608.09265v1 Announce Type: cross Abstract: Optimal transport and Gromov--Wasserstein distances are useful tools for comparing probability measures and metric measure spaces, but their balanced formulations force all mass to be matched. This constraint is often too strong f…
