The Policy Gradient Theorem

# The Policy Gradient Theorem: Your Definitive Guide to Smarter Reinforcement Learning Imagine training an AI to play a complex game like Go or master the intricacies of robotic control. You want it to learn the optimal strategy directly, without explicitly defining the value of each state. This is where policy gradient methods come in, and at the heart of these methods lies **The Policy Gradient Theorem**. This theorem provides a way to directly optimize the policy (the AI's strategy) by esti
