Questions and Answers

In reinforcement learning, what is the role of the reward function?

  • To define the agent's utility (correct)
  • To specify the available actions
  • To control the behavior of the environment
  • To determine the state of the agent
  • What is the primary goal of an agent in reinforcement learning?

  • To ignore the available actions
  • To maximize expected rewards (correct)
  • To minimize observed samples
  • To avoid feedback in the form of rewards
  • In the context of reinforcement learning, what is the main purpose of learning based on observed samples of outcomes?

  • To control the behavior of the environment
  • To inform the agent's decision-making process (correct)
  • To minimize the role of the reward function
  • To define the state of the agent
  • What is the key aspect of reinforcement learning illustrated in the example of 'Learning to Walk'?
