A research team is training a language model to act as a helpful assistant using methods from reinforcement learning. One researcher is focused on analyzing the model's 'policy' (π) for generating a response given a user's query. Another researcher is analyzing the model's 'conditional probability distribution' (Pr) over all possible responses for the same query. What is the relationship between the 'policy' and the 'conditional probability distribution' in this context?

When applying reinforcement learning to a language model, the model's policy, denoted as π(y|x), is a separate computational function that is trained to approximate the model's core conditional probability distribution, Pr(y|x).
