Subspace Detours Meet Gromov–Wasserstein
Subspace Detours Meet Gromov–Wasserstein
In the context of optimal transport (OT) methods, the subspace detour approach was recently proposed by Muzellec and Cuturi. It consists of first finding an optimal plan between the measures projected on a wisely chosen subspace and then completing it in a nearly optimal transport plan on the whole space. …
