Minimax and adaptive estimation of the Wigner function in quantum homodyne tomography with noisy data
Karim Lounici, Katia Meziani, Gabriel Peyré
In quantum optics, the quantum state of a light beam is represented through the Wigner function, a density on which may take negative values but must respect intrinsi…

Entropic Wasserstein Gradient Flows
Gabriel Peyré
This article details a novel numerical scheme to approximate gradient flows for optimal transport (i.e. Wasserstein) metrics. These flows have proved useful to tackle theoretically…

Stein COnsistent Risk Estimator (SCORE) for hard thresholding
Charles-Alban Deledalle, Gabriel Peyré, Jalal Fadili
In this work, we construct a risk estimator for hard thresholding which can be used as a basis to solve the difficult task of automatically selecting the threshold. As hard thresho…
