ott.initializers.quadratic#

Two families of initializers are described in the following to provide the first iteration of Gromov-Wasserstein solvers. They apply respectively to the simpler GW entropic solver [Peyré et al., 2016] and its low-rank formulation [Scetbon et al., 2022].

Gromov-Wasserstein Initializers#

initializers.QuadraticInitializer(**kwargs)

Initialize a linear problem locally around \(ab^T\) initializer.

initializers.LRQuadraticInitializer(...)

Wrapper that wraps low-rank Sinkhorn initializers.
