Generalized Wasserstein Flow Matching: Transport Plans, Everywhere, All at Once

Moritz Piening, Richard Duong, Gabriele Steidl

Flow matching has recently emerged as a flexible and efficient framework for generative modelling by learning deterministic transport dynamics between probability measures. In this…

Paired Wasserstein Autoencoders for Conditional Sampling

Moritz Piening, Matthias Chung

Generative autoencoders learn compact latent representations of data distributions through jointly optimized encoder--decoder pairs. In particular, Wasserstein autoencoders (WAEs)…

Slicing Wasserstein Over Wasserstein Via Functional Optimal Transport

Moritz Piening, Robert Beinert

Wasserstein distances define a metric between probability measures on arbitrary metric spaces, including meta-measures (measures over measures). The resulting Wasserstein over Wass…

A Novel Sliced Fused Gromov-Wasserstein Distance

Moritz Piening, Robert Beinert

The Gromov--Wasserstein (GW) distance and its fused extension (FGW) are powerful tools for comparing heterogeneous data. Their computation is, however, challenging since both dista…

Slicing the Gaussian Mixture Wasserstein Distance

Moritz Piening, Robert Beinert

Gaussian mixture models (GMMs) are widely used in machine learning for tasks such as clustering, classification, image reconstruction, and generative modeling. A key challenge in w…

Joint Metric Space Embedding by Unbalanced OT with Gromov-Wasserstein Marginal Penalization

Florian Beier, Moritz Piening, Robert Beinert +1

We propose a new approach for unsupervised alignment of heterogeneous datasets, which maps data from two different domains without any known correspondences to a common metric spac…
