Can Push-forward Generative Models Fit Multimodal Distributions?

no code implementations29 Jun 2022 Antoine Salmona, Valentin De Bortoli, Julie Delon, Agnès Desolneux

More precisely, we show that the total variation distance and the Kullback-Leibler divergence between the generated and the data distribution are bounded from below by a constant depending on the mode separation and the Lipschitz constant.

On quantitative Laplace-type convergence results for some exponential probability measures, with two applications

no code implementations25 Oct 2021 Valentin De Bortoli, Agnès Desolneux

Classical results require the invertibility of the Hessian of $U$ in order to establish such asymptotics.

Exact Sampling of Determinantal Point Processes without Eigendecomposition

no code implementations23 Feb 2018 Claire Launay, Bruno Galerne, Agnès Desolneux

The exact algorithm to sample DPPs uses the spectral decomposition of $K$, a computation that becomes costly when dealing with a high number of points.

Point Processes

A survey of exemplar-based texture synthesis

no code implementations22 Jul 2017 Lara Raad, Axel Davy, Agnès Desolneux, Jean-Michel Morel

The two main approaches are statistics-based methods and patch re-arrangement methods.
