The Coupling Within: Flow Matching via Distilled Normalizing Flows

arXiv:2603.09014v1 Announce Type: new Abstract: Flow models have rapidly become the go-to method for training and deploying large-scale generators, owing their success to inference-time flexibility via adjustable integration steps. A crucial ingredient in flow training is the choice of coupling…

Global universality via discrete-time signatures

arXiv:2603.09773v1 Announce Type: cross Abstract: We establish global universal approximation theorems on spaces of piecewise linear paths, stating that linear functionals of the corresponding signatures are dense with respect to $L^p$- and weighted norms, under an integrability condition on the…

DUEL: Exact Likelihood for Masked Diffusion via Deterministic Unmasking

arXiv:2603.01367v2 Announce Type: replace Abstract: Masked diffusion models (MDMs) generate text by iteratively selecting positions to unmask and then predicting tokens at those positions. Yet MDMs lack proper likelihood evaluation: the evidence lower bound (ELBO) is not only a loose…
