On importance sampling and independent Metropolis-Hastings with an unbounded weight function

George Deligiannidis, Pierre E. Jacob, El Mahdi Khribch +1

Importance sampling and independent Metropolis-Hastings are among the fundamental building blocks of Monte Carlo methods. Both require a proposal distribution that globally approxi…

Minimax optimality of deep neural networks on dependent data via PAC-Bayes bounds

Pierre Alquier, William Kengne

In a groundbreaking work, Schmidt-Hieber (2020) proved the minimax optimality of deep neural networks with ReLu activation for least-square regression estimation over a large class…

Learning with Importance Weighted Variational Inference

Kamélia Daudel, François Roueff

Several variational bounds involving importance weighting ideas generalize the Evidence Lower BOund (ELBO) for marginal likelihood optimization, such as the Importance-weighted Aut…

The Multi-Commodity Flow Problem with Outsourcing Decisions

Elena Fernandez, Ivana Ljubic, Nicolas Zerega

We address a new prize-collecting problem of routing commodities in a given network with hub and non-hub nodes, in which the service of the non-hub nodes will be outsourced to thir…

One-Bit Total Variation Denoising over Networks with Applications to Partially Observed Epidemics

Claire Donnat, Olga Klopp, Nicolas Verzelen

This paper introduces a novel approach for epidemic nowcasting and forecasting over networks using total variation (TV) denoising, a method inspired by classical signal processing…

Generalized multi-view model: Adaptive density estimation under low-rank constraints

Julien Chhor, Olga Klopp, Alexandre Tsybakov

We study the problem of bivariate discrete or continuous probability density estimation under low-rank constraints.For discrete distributions, we assume that the two-dimensional ar…
