// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Mean Squared Error
A common metric that measures the average of the squared differences between predicted and actual values, penalizing larger errors more heavily.
TECHNICAL DEFINITION
Mean Squared Error (MSE) is a widely used regression evaluation metric that computes the average of the squared differences between the predicted values and the actual ground truth values, heavily penalizing larger errors and providing a differentiable loss function for optimization.
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.
