ShiQ: Bringing back Bellman to LLMs

Pierre Clavier, Nathan Grinsztajn, Raphael Avalos +8

The fine-tuning of pre-trained large language models (LLMs) using reinforcement learning (RL) is generally formulated as direct policy optimization. This approach was naturally fav…

Contrastive Policy Gradient: Aligning LLMs on sequence-level scores in a supervised-friendly fashion

Yannis Flet-Berliac, Nathan Grinsztajn, Florian Strub +8

Reinforcement Learning (RL) has been used to finetune Large Language Models (LLMs) using a reward model trained from preference data, to better align with human judgment. The recen…

Averaging log-likelihoods in direct alignment

Nathan Grinsztajn, Yannis Flet-Berliac, Mohammad Gheshlaghi Azar +8

To better align Large Language Models (LLMs) with human judgment, Reinforcement Learning from Human Feedback (RLHF) learns a reward model and then optimizes it using regularized RL…
