9.2.3 - Bellman Equations

Learning

Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Define the Bellman Equation and its purpose in reinforcement learning.

πŸ’‘ Hint: Consider how rewards from immediate actions relate to future actions and states.

Question 2

Easy

What does the discount factor (Ξ³) do?

πŸ’‘ Hint: Think about why we might want to prioritize immediate rewards over future uncertain rewards.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does the Bellman Equation relate to in reinforcement learning?

  • Value of current states
  • Immediate rewards only
  • Exploration strategies

πŸ’‘ Hint: Think about how values propagate through states due to actions taken.

Question 2

True or False: The discount factor (Ξ³) can only take values greater than 1.

  • True
  • False

πŸ’‘ Hint: Revisit the purpose of the discount factor.

Challenge Problems

Push your limits with challenges.

Question 1

Propose a complex scenario where an agent must decide between multiple actions with unknown rewards. Use the Bellman Equation to calculate the state values and determine the optimal action.

πŸ’‘ Hint: Break down the problem: represent the states, possible actions, and their rewards clearly.

Question 2

You have a grid-world agent that receives a reward of 10 for reaching the goal but incurs a penalty of 1 for each step taken. Formulate the Bellman Equation to derive the optimal path and explain how the discount factor influences the results.

πŸ’‘ Hint: Consider how both immediate and future rewards need to be evaluated to engage the optimal path.
