Definition
Helpsteer2 is a curated dataset released by NVIDIA that contains pairwise comparisons of responses generated by large language models. It focuses on multi-dimensional human preferences, such as helpfulness, honesty, and harmlessness. The dataset is primarily used to train reward models that guide the fine-tuning of LLMs via Reinforcement Learning from Human Feedback (RLHF). Its structured annotations allow researchers to evaluate and improve model alignment with human values effectively.
