Data Collection for Reward Modeling in RLHF
The initial step in training a reward model is to gather a dataset of human feedback. This process starts by using a Large Language Model to generate several different candidate outputs for a given input prompt, x. These outputs are then evaluated by humans, and their feedback can be collected using a variety of methods.

Data Collection for Reward Modeling in RLHF
A machine learning team is implementing a training process that uses human feedback to align a language model. They have access to two base models: a general-purpose pre-trained language model (Model A) and a version of that model that has been further fine-tuned on a set of instructions (Model B). For the first stage of their process, which of the following initialization plans is correct for the policy, reference, reward, and value models?

Techniques for Generating Diverse Outputs in RLHF
A team is developing a system to align a language model with human preferences. Their data collection process involves providing a prompt to an existing, fine-tuned model, which then generates a single response. A human labeler then assigns a quality score from 1 to 10 to this single response. This process is repeated for thousands of different prompts. What is the most significant flaw in this methodology for the purpose of creating a robust preference-based reward model?
