Reward Model Learning in RLHF

A team is training a conversational agent to be more helpful. Their strategy involves having a human user interact with the agent. After each response from the agent, the human provides a numerical score indicating its quality. This score is immediately used as a signal to update the agent's internal strategy for generating the next response. This direct-feedback loop is repeated thousands of times. The team observes that this training process is prohibitively slow and costly. Based on the typical two-stage process for this kind of training, what is the most significant flaw in the team's approach?

A common method for aligning a language model with human preferences involves two major phases. Arrange the following descriptions of these phases in the correct chronological order.

A team is implementing a system to align a language model with human preferences. The process involves several distinct activities. Match each activity described below to the primary learning stage it belongs to.
