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…
A remark on Kashin's discrepancy argument and partial coloring in the Komlós conjecture
Afonso S. Bandeira, Antoine Maillard, Nikita Zhivotovskiy
In this expository note, we discuss an early partial coloring result of B. Kashin [C. R. Acad. Bulgare Sci., 1985]. Although this result only implies Spencer's six standard deviati…
Phase Retrieval: From Computational Imaging to Machine Learning
Jonathan Dong, Lorenzo Valzania, Antoine Maillard +3
Phase retrieval consists in the recovery of a complex-valued signal from intensity-only measurements. As it pervades a broad variety of applications, many researchers have striven…
Optimal denoising of rotationally invariant rectangular matrices
Emanuele Troiani, Vittorio Erba, Florent Krzakala +2
In this manuscript we consider denoising of large rectangular matrices: given a noisy observation of a signal matrix, what is the best way of recovering the signal matrix itself? F…
