Denoising Score Matching in Diffusion Models: The Effect of Rank Constraints on Generalization
Anand Jerry George, Nicolas Macris
Architectural biases restrict the class of functions that a diffusion score network can represent, but their effect on generalization remains poorly understood. We study denoising…

Separable decompositions of 2xn states with operator Schmidt rank three
Perrine Vantalon, Nicolas Macris
We prove that every bipartite state of a qubit coupled to an -level system whose operator Schmidt rank equals three can be written as a mixture of pure prod…

Asymptotic Learning Curves for Diffusion Models with Random Features Score and Manifold Data
Anand Jerry George, Nicolas Macris
We study the theoretical behavior of denoising score matching--the learning task associated to diffusion models--when the data distribution is supported on a low-dimensional manifo…
