Gromov-wasserstein discrepancy

Webapproach for scaling up the GW distance is Sliced Gromov-Wasserstein (SGW) discrepancy (Vayer et al., 2024), which leverages on random projections on 1D and on a closed-form solution of the 1D-Gromov-Wasserstein. In this paper, we take a different approach for measuring the discrepancy between two heteroge-neous distributions. WebEnter the email address you signed up with and we'll email you a reset link.
