Establishing the Initial Policy in RLHF

A team is developing a language model designed to align with human preferences. They are following a standard four-stage process. Arrange the following stages in the correct chronological order.

A development team is using a four-stage process to align a language model with human preferences. They collect a large dataset where human annotators consistently rank verbose and evasive responses as low quality. This dataset is then used to train a reward model. Finally, the language model is fine-tuned using reinforcement learning, with the reward model providing the optimization signal. However, the final, aligned language model still frequently produces verbose and evasive outputs. Which s
