High-probability zeroth-order online convex optimisation beyond Euclidean geometry

David Janz, El-Mahdi El-Mhamdi, Arya Akhavan

We study online convex optimisation with -Lipschitz losses, -regularised FTRL, and randomised two-point finite-difference gradient estimators based on cone-measure…

Winter Soldier: Backdooring Language Models at Pre-Training with Indirect Data Poisoning

Wassim Bouaziz, Mathurin Videau, Nicolas Usunier +1

The pre-training of large language models (LLMs) relies on massive text datasets sourced from diverse and difficult-to-curate origins. Although membership inference attacks and hid…

On Monotonicity in AI Alignment

Gilles Bareilles, Julien Fageot, Lê-Nguyên Hoang +4

Comparison-based preference learning has become central to the alignment of AI models with human preferences. However, these methods may behave counterintuitively. After empiricall…

The Strong, Weak and Benign Goodhart's law. An independence-free and paradigm-agnostic formalisation

Adrien Majka, El-Mahdi El-Mhamdi

Goodhart's law is a famous adage in policy-making that states that ``When a measure becomes a target, it ceases to be a good measure''. As machine learning models and the optimisat…

Targeted Data Poisoning for Black-Box Audio Datasets Ownership Verification

Wassim Bouaziz, El-Mahdi El-Mhamdi, Nicolas Usunier

Protecting the use of audio datasets is a major concern for data owners, particularly with the recent rise of audio deep learning models. While watermarks can be used to protect th…

On the Byzantine Fault Tolerance of signSGD with Majority Vote

Emanuele Mengoli, Luzius Moll, Virgilio Strozzi +1

In distributed learning, sign-based compression algorithms such as signSGD with majority vote provide a lightweight alternative to SGD with an additional advantage: fault tolerance…

A Case for Specialisation in Non-Human Entities

El-Mahdi El-Mhamdi, Lê-Nguyên Hoang, Mariame Tighanimine

With the rise of large multi-modal AI models, fuelled by recent interest in large language models (LLMs), the notion of artificial general intelligence (AGI) went from being restri…

Approaching the Harm of Gradient Attacks While Only Flipping Labels

Abdessamad El-Kabid, El-Mahdi El-Mhamdi

Machine learning systems deployed in distributed or federated environments are highly susceptible to adversarial manipulations, particularly availability attacks -- rendering the t…

Stop treating `AGI' as the north-star goal of AI research

Borhane Blili-Hamelin, Christopher Graziul, Leif Hancox-Li +13

The AI research community plays a vital role in shaping the scientific, engineering, and societal goals of AI research. In this position paper, we argue that focusing on the highly…
