Agentic Adversarial QA for Improving Domain-Specific LLMs

Vincent Grari, Ciprian Tomoiaga, Sylvain Lamprier +2

Large Language Models (LLMs), despite extensive pretraining on broad internet corpora, often struggle to adapt effectively to specialized domains. There is growing interest in fine…

Offline Reinforcement Learning of High-Quality Behaviors Under Robust Style Alignment

Mathieu Petitbois, Rémy Portelas, Sylvain Lamprier

We study offline reinforcement learning of style-conditioned policies using explicit style supervision via subtrajectory labeling functions. In this setting, aligning style with hi…
