Contractive coupling rates and curvature lower bounds for Markov chains

Francesco Pedrotti

Contractive coupling rates have been recently introduced by Conforti as a tool to establish convex Sobolev inequalities (including modified log-Sobolev and Poincaré inequality) for…

Improved Convergence of Score-Based Diffusion Models via Prediction-Correction

Francesco Pedrotti, Jan Maas, Marco Mondelli

Score-based generative models (SGMs) are powerful tools to sample from complex data distributions. Their underlying idea is to (i) run a forward process for time by adding no…

Local Conditions for Global Convergence of Gradient Flows and Proximal Point Sequences in Metric Spaces

Lorenzo Dello Schiavo, Jan Maas, Francesco Pedrotti

This paper deals with local criteria for the convergence to a global minimiser for gradient flow trajectories and their discretisations. To obtain quantitative estimates on the spe…
