Off-Policy Corrected Reward Modeling for Reinforcement Learning from Human Feedback

Johannes Ackermann, Takashi Ishida, Masashi Sugiyama

Reinforcement Learning from Human Feedback (RLHF) allows us to train models, such as language models (LMs), to follow complex human preferences. In RLHF for LMs, we first train an…

CapBencher: Give Your LLM Benchmark a Built-in Alarm for Test-Set Overfitting

Takashi Ishida, Thanawat Lodkaew, Ikko Yamane

Publishing a large language model (LLM) benchmark (especially its ground-truth answers) on the Internet risks contaminating future LLMs and enabling evaluation gaming: it may be un…
