Generalization, memorization, and overfitting for diffusion models trained in the lazy high-dimensional regime
Hugo Latourelle-Vigeant, Sinho Chewi, Aram-Alexandre Pooladian +2
Modern score-based generative models have achieved remarkable empirical success in high-dimensional tasks such as image, audio, and video synthesis. These models reduce distributio…

Statistical-Computational Trade-offs in Learning Multi-Index Models via Harmonic Analysis
Hugo Latourelle-Vigeant, Theodor Misiakiewicz
We study the problem of learning multi-index models (MIMs), where the label depends on the input only through an unknown -dimensional…

Dyson Equation for Correlated Linearizations and Test Error of Random Features Regression
Hugo Latourelle-Vigeant, Elliot Paquette
This paper develops some theory of the Dyson equation for correlated linearizations and uses it to solve a problem on asymptotic deterministic equivalent for the test error in rand…
