FlashSinkhorn 2 introduces a two-stage block-sparse GPU solver for entropic optimal transport that scales to 1.34e8-particle point clouds, solving them on a single A100 to a marginal residual below 0.01 in under 2.5 hours — claimed to be the largest discrete EOT problem solved at this accuracy within hours. An open-source implementation is released.
This paper proposes BaryFM, a flow matching model that learns to approximate the entire Wasserstein simplex — the full family of Wasserstein barycenters over the simplex of weight vectors — rather than a fixed-weight barycenter. BaryFM achieves the best average rank among 15 methods across 10 domain adaptation benchmarks and is validated on tasks including generalization, Bayesian posterior aggregation, and algorithmic fairness.
The paper proposes OTROPE, a likelihood-free off-policy evaluation method for LLMs that uses optimal transport to align limited human-labeled behavior-policy samples with unlabeled target-policy samples in semantic space, yielding a doubly robust-style evaluator that outperforms baselines under distribution shift.
ATLAS is a training objective for latent world models that preserves relational geometry from encoder representations into the planning latent while calibrating its marginal distribution via Wasserstein-2 transport (WEMReg). Instantiated in LeWM, it improves goal-reaching success on PushT, TwoRoom, and OGBench-Cube benchmarks, particularly on higher-novelty episodes.

The paper introduces Reward-Weighted Transport Distillation (RWTD), a post-training method for one-step generative models that needs only generated samples and scalar rewards, blending tilted current and reference distributions via feature-space optimal transport. It boosts the GenEval score of the SanaSprint 1.6B one-step backbone from 0.73 to 0.80 while preserving compositional capabilities.
This paper introduces Riemannian Wasserstein Entropic Flow Matching (RWEFM), a generative framework for modeling probability distributions on Riemannian manifolds, with applications in scientific domains like single-cell biology and protein conformations.
