Robustness Cannot be Reduced to Regularization: Studying Adversarial Training Beyond the Linear Case

David A. R. Robin, Rafael Pinot, Yann Chevaleyre

The vulnerability of ML models to adversarial examples has recently emerged as a major concern. While adversarial training is one of the most effective countermeasures to this issu…

MetagenBERT: a Transformer-based Architecture using Foundational genomic Large Language Models for novel Metagenome Representation

Gaspar Roy, Eugeni Belda, Baptiste Hennecart +3

Metagenomic disease prediction commonly relies on species abundance tables derived from large, incomplete reference catalogs, constraining resolution and discarding valuable inform…

Improving Diversity in Language Models: When Temperature Fails, Change the Loss

Alexandre Verine, Florian Le Bronnec, Kunhao Zheng +3

Increasing diversity in language models is a challenging yet essential objective. A common approach is to raise the decoding temperature. In this work, we investigate this approach…

Lattice Climber Attack: Adversarial attacks for randomized mixtures of classifiers

Lucas Gnecco-Heredia, Benjamin Negrevergne, Yann Chevaleyre

Finite mixtures of classifiers (a.k.a. randomized ensembles) have been proposed as a way to improve robustness against adversarial attacks. However, existing attacks have been show…

Improving Discriminator Guidance in Diffusion Models

Alexandre Verine, Ahmed Mehdi Inane, Florian Le Bronnec +2

Discriminator Guidance has become a popular method for efficiently refining pre-trained Score-Matching Diffusion models. However, in this paper, we demonstrate that the standard im…
