Sampling and Uniqueness Sets in Graphon Signal Processing

arXiv:2401.06279v3 Announce Type: replace Abstract: In this work, we study the properties of sampling sets on families of large graphs by leveraging the theory of graphons and graph limits. To this end, we extend to graphon signals the notion of…

Sinkhorn-Drifting Generative Models

arXiv:2603.12366v1 Announce Type: new Abstract: We establish a theoretical link between the recently proposed “drifting” generative dynamics and gradient flows induced by the Sinkhorn divergence. In a particle discretization, the drift field admits a cross-minus-self decomposition: an attractive term toward…

Epistemic diversity across language models mitigates knowledge collapse

arXiv:2512.15011v2 Announce Type: replace Abstract: As artificial intelligence (AI) becomes more widely used, concerns are growing that model collapse could lead to knowledge collapse, i.e. a degradation to a narrow and inaccurate set of ideas. Prior work has demonstrated single-model…
