Reinforcement Learning and Deep RL Python Theory and Projects - Target Network and Recap

The video tutorial explains the importance of selecting random batches from replay memory to avoid correlation issues in training neural networks. It introduces the concept of a target network, which is a replica of the policy network, and its role in stabilizing the learning process. The tutorial details the calculation of the loss function using Q values from both the policy and target networks, emphasizing the Bellman equation. It concludes with an overview of the algorithm and outlines the next steps for implementation in Python.

Describe the role of experience in reinforcement learning and what it typically contains.

Why is it necessary to freeze the weights of the policy network when creating a target network?

What steps are involved in updating the target network after a certain number of steps?

How does the concept of instability in Q-values relate to the use of target networks?
