// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

Hyperparameter

These are settings that are chosen before a machine learning model starts learning, like the learning rate or the number of layers in a neural network. They are not learned by the model itself.

TECHNICAL DEFINITION

A configuration variable external to the model whose value is set prior to the commencement of the learning process, influencing the training algorithm's behavior and the model's architecture.

BACKGROUND

In machine learning, reinforcement learning from human feedback (RLHF) is a technique to align an intelligent agent with human preferences. It involves training a reward model to represent preferences, which can then be used to train other models through reinforcement learning.
