Diffusion Models for Interferometric Satellite Aperture Radar

1 code implementation31 Aug 2023 Alexandre Tuel, Thomas Kerdreux, Claudia Hulbert, Bertrand Rouet-Leduc

Probabilistic Diffusion Models (PDMs) have recently emerged as a very promising class of generative models, achieving high performance in natural image generation.

Autonomous Detection of Methane Emissions in Multispectral Satellite Data Using Deep Learning

no code implementations21 Aug 2023 Bertrand Rouet-Leduc, Thomas Kerdreux, Alexandre Tuel, Claudia Hulbert

Methane is one of the most potent greenhouse gases, and its short atmospheric half-life makes it a prime target to rapidly curb global warming.

Efficient Online-Bandit Strategies for Minimax Learning Problems

no code implementations28 May 2021 Christophe Roux, Elias Wirth, Sebastian Pokutta, Thomas Kerdreux

Several learning problems involve solving min-max problems, e. g., empirical distributional robust learning or learning with non-standard aggregated losses.

Linear Bandits on Uniformly Convex Sets

no code implementations10 Mar 2021 Thomas Kerdreux, Christophe Roux, Alexandre d'Aspremont, Sebastian Pokutta

Linear bandit algorithms yield $\tilde{\mathcal{O}}(n\sqrt{T})$ pseudo-regret bounds on compact convex action sets $\mathcal{K}\subset\mathbb{R}^n$ and two types of structural assumptions lead to better pseudo-regret bounds.

Generating Structured Adversarial Attacks Using Frank-Wolfe Method

no code implementations15 Feb 2021 Ehsan Kazemi, Thomas Kerdreux, Liquang Wang

White box adversarial perturbations are generated via iterative optimization algorithms most often by minimizing an adversarial loss on a $\ell_p$ neighborhood of the original image, the so-called distortion set.

Adversarial Robustness

Local and Global Uniform Convexity Conditions

no code implementations9 Feb 2021 Thomas Kerdreux, Alexandre d'Aspremont, Sebastian Pokutta

We review various characterizations of uniform convexity and smoothness on norm balls in finite-dimensional spaces and connect results stemming from the geometry of Banach spaces with \textit{scaling inequalities} used in analysing the convergence of optimization methods.

Diptychs of human and machine perceptions

no code implementations12 Oct 2020 Vivien Cabannes, Thomas Kerdreux, Louis Thiry

We propose visual creations that put differences in algorithms and humans \emph{perceptions} into perspective.

Trace-Norm Adversarial Examples

no code implementations2 Jul 2020 Ehsan Kazemi, Thomas Kerdreux, Liqiang Wang

White box adversarial perturbations are sought via iterative optimization algorithms most often minimizing an adversarial loss on a $l_p$ neighborhood of the original image, the so-called distortion set.

Interactive Neural Style Transfer with Artists

1 code implementation14 Mar 2020 Thomas Kerdreux, Louis Thiry, Erwan Kerdreux

We present interactive painting processes in which a painter and various neural style transfer algorithms interact on a real canvas.

Reconstructing Latent Orderings by Spectral Clustering

1 code implementation18 Jul 2018 Antoine Recanati, Thomas Kerdreux, Alexandre d'Aspremont

We tackle the task of retrieving linear and circular orderings in a unifying framework, and show how a latent ordering on the data translates into a filamentary structure on the Laplacian embedding.

Frank-Wolfe with Subsampling Oracle

no code implementations ICML 2018 Thomas Kerdreux, Fabian Pedregosa, Alexandre d'Aspremont

The first algorithm that we propose is a randomized variant of the original FW algorithm and achieves a $\mathcal{O}(1/t)$ sublinear convergence rate as in the deterministic counterpart.
