Reinforcement Learning and Deep RL Python Theory and Projects - Policy Network Explained

The video tutorial explains the concept of a policy network in deep reinforcement learning, focusing on its structure, inputs, and outputs. It describes the importance of context in input data, using the example of the cart-pole problem. The tutorial details how a sequence of states is fed into the network and how the output layer generates Q values for decision-making. The video concludes with a discussion on forward propagation and hints at future topics like target networks and replay memory.
