Webment algorithm based on the maximum mean discrepancy (MMD) measure, called MMD-MA, which can integrate dif-ferent types of single-cell measurements. Another method, ... SCOT uses Gromov Wasserstein optimal transport, which preserves local neighborhood geometry when moving data points. The output of this transport problem is a matrix of WebMay 24, 2024 · To that extent, we derive a novel OT discrepancy called Sliced Gromov-Wasserstein (S G W). It is similar in spirit to the Sliced Wasserstein distance as it relies on the exact computation of 1D G W distances of distributions projected onto …
Gromov-Wasserstein Factorization Models for Graph Clustering
WebTo address this issue, we propose measuring the perturbation with the orthogonal Gromov-Wasserstein discrepancy, and building its Fenchel biconjugate to facilitate convex optimization. Our key insight is drawn from the matching loss whose root connects two variables via a monotone operator, and it yields a tight outer convex approximation for ... WebMay 11, 2024 · By doing so, we derive the spherical sliced fused Gromov Wasserstein (SSFG) discrepancy which is further proved as a pseudo metric in the space of probability distributions. Similar to the SFG, the SSFG has a fast computational speed and does not suffer from the curse of dimensionality. Moreover, the SSFG is the generalization and the ... cosby statement
