Multilingual Self-Taught Faithfulness Evaluators

Carlo Alfano, Aymen Al Marjani, Zeno Jonke +3

The growing use of large language models (LLMs) has increased the need for automatic evaluation systems, particularly to address the challenge of information hallucination. Althoug…

Differentially Private Best-Arm Identification

Achraf Azize, Marc Jourdan, Aymen Al Marjani +1

Best Arm Identification (BAI) problems are progressively used for data-sensitive applications, such as designing adaptive clinical trials, tuning hyper-parameters, and conducting u…

On the Complexity of Differentially Private Best-Arm Identification with Fixed Confidence

Achraf Azize, Marc Jourdan, Aymen Al Marjani +1

Best Arm Identification (BAI) problems are progressively used for data-sensitive applications, such as designing adaptive clinical trials, tuning hyper-parameters, and conducting u…

Active Coverage for PAC Reinforcement Learning

Aymen Al-Marjani, Andrea Tirinzoni, Emilie Kaufmann

Collecting and leveraging data with good coverage properties plays a crucial role in different aspects of reinforcement learning (RL), including reward-free exploration and offline…

On the complexity of All -Best Arms Identification

Aymen Al Marjani, Tomáš Kocák, Aurélien Garivier

We consider the question introduced by \cite{Mason2020} of identifying all the -optimal arms in a finite stochastic multi-armed bandit with Gaussian rewards. We give t…

Navigating to the Best Policy in Markov Decision Processes

Aymen Al Marjani, Aurélien Garivier, Alexandre Proutiere

We investigate the classical active pure exploration problem in Markov Decision Processes, where the agent sequentially selects actions and, from the resulting system trajectory, a…
