On free energy barriers in Gaussian priors and failure of cold start MCMC for high-dimensional unimodal distributions
Afonso S. Bandeira, Antoine Maillard, Richard Nickl +1
We exhibit examples of high-dimensional unimodal posterior distributions arising in non-linear regression models with Gaussian process priors for which MCMC methods can take an exp…
Phase retrieval in high dimensions: Statistical and computational phase transitions
Antoine Maillard, Bruno Loureiro, Florent Krzakala +1
We consider the phase retrieval problem of reconstructing a -dimensional real or complex signal from (possibly noisy) observations $Y_μ= | \sum_{i=1}^n…
The spiked matrix model with generative priors
Benjamin Aubin, Bruno Loureiro, Antoine Maillard +2
Using a low-dimensional parametrization of signals is a generic and powerful way to enhance performance in signal processing and statistical inference. A very popular and widely ex…
