Question 1

What is the main improvement of TD3 over DDPG?

  • It uses a single Q-network.
  • It updates the policy more frequently.
  • It utilizes twin Q-networks.
  • It ignores overestimation bias.

πŸ’‘ Hint: Focus on the mechanisms TD3 implements to resolve its predecessors' issues.

Question 2

True or False: Delayed policy updates make TD3 learn slower but more reliably.

  • True
  • False

πŸ’‘ Hint: Think about the balance between learning rate and stability.
