Shaping Language Models with Cognitive Insights

RLHF-Blender: A Configurable Interactive Interface for Learning from Diverse Human Feedback

[AAMAS 2025] Privacy-preserving and Personalized RLHF, with convergence guarantees. The Code contains experiments for training multiple instances of GPT-2 for personalized sentiment aligned text generation.

Acceleration framework for Human Alignment Learning

[TSMC] Ask-AC: An Initiative Advisor-in-the-Loop Actor-Critic Framework

This repository contains the implementation of a Reinforcement Learning with Human Feedback (RLHF) system using custom datasets. The project utilizes the trlX library for training a preference model that integrates human feedback directly into the optimization of language models.

LMRax is a framework built on JAX to train transformers language models by reinforcement learning, along with the reward model training.
