The IICT-Yverdon System for the WMT 2021 Unsupervised MT and Very Low Resource Supervised MT Task

no code implementations WMT (EMNLP) 2021 Àlex R. Atrio, Gabriel Luthier, Axel Fahy, Giorgos Vernikos, Andrei Popescu-Belis, Ljiljana Dolamic

We then present the application of this system to the 2021 task for low-resource supervised Upper Sorbian (HSB) to German translation, in both directions.

A Classification-Guided Approach for Adversarial Attacks against Neural Machine Translation

no code implementations29 Aug 2023 Sahar Sadrizadeh, Ljiljana Dolamic, Pascal Frossard

To evaluate the robustness of NMT models to our attack, we propose enhancements to existing black-box word-replacement-based attacks by incorporating output translations of the target NMT model and the output logits of a classifier within the attack process.

A Relaxed Optimization Approach for Adversarial Attacks against Neural Machine Translation Models

no code implementations14 Jun 2023 Sahar Sadrizadeh, Clément Barbier, Ljiljana Dolamic, Pascal Frossard

First, we propose an optimization problem to generate adversarial examples that are semantically similar to the original sentences but destroy the translation generated by the target NMT model.

Evolutionary Algorithms in the Light of SGD: Limit Equivalence, Minima Flatness, and Transfer Learning

no code implementations20 May 2023 Andrei Kucharavy, Rachid Guerraoui, Ljiljana Dolamic

In this paper, we show that a class of evolutionary algorithms (EAs) inspired by the Gillespie-Orr Mutational Landscapes model for natural evolution is formally equivalent to SGD in certain settings and, in practice, is well adapted to large ANNs.

Byzantine-Resilient Learning Beyond Gradients: Distributing Evolutionary Search

no code implementations20 Apr 2023 Andrei Kucharavy, Matteo Monti, Rachid Guerraoui, Ljiljana Dolamic

We then leverage this definition to show that a general class of gradient-free ML algorithms - ($1,\lambda$)-Evolutionary Search - can be combined with classical distributed consensus algorithms to generate gradient-free byzantine-resilient distributed learning algorithms.

Fundamentals of Generative Large Language Models and Perspectives in Cyber-Defense

no code implementations21 Mar 2023 Andrei Kucharavy, Zachary Schillaci, Loïc Maréchal, Maxime Würsch, Ljiljana Dolamic, Remi Sabonnadiere, Dimitri Percia David, Alain Mermoud, Vincent Lenders

Generative Language Models gained significant attention in late 2022 / early 2023, notably with the introduction of models refined to act consistently with users' expectations of interactions with AI (conversational models).

TransFool: An Adversarial Attack against Neural Machine Translation Models

1 code implementation2 Feb 2023 Sahar Sadrizadeh, Ljiljana Dolamic, Pascal Frossard

Deep neural networks have been shown to be vulnerable to small perturbations of their inputs, known as adversarial attacks.
