Policy Gradient

Fact

A reinforcement learning method that improves choices to earn higher long-term reward.

In Plain Words

Policy Gradient coaches AI like a Mario Kart parent. It skips every tiny lecture and rewards the whole good lap.

It updates the AI’s action rules, so rewarded choices happen more often. You meet it in robot control and RLHF.

RLHF
RLHF often uses Policy Gradient to move the model toward rewarded answers.

SGD
Policy Gradient finds the gradient, then SGD often updates the weights.

Agent
Policy Gradient trains an Agent through many tries and rewards.
