5. What is the term for the method in which an RL agent explores the environment to learn optimal actions?

Exploitation

Generalization

Exploration

Policy Optimization

Exploration refers to the process of the agent exploring the environment to learn optimal actions.

Explanation

Exploration refers to the process of the agent exploring the environment to learn optimal actions.

6. In RL, what is a policy?

A set of states

A sequence of actions

A mapping of states to actions

A series of rewards

A policy is a mapping of states to actions, representing the agent's decision-making.

Explanation

A policy is a mapping of states to actions, representing the agent's decision-making.

7. What is the exploration-exploitation trade-off in RL?

Balancing the model complexity

Balancing the learning rate

Balancing immediate and future rewards

Balancing between exploring and exploiting

The exploration-exploitation trade-off involves finding the balance between exploring the environment to learn and exploiting the known knowledge to maximize rewards.

Explanation

The exploration-exploitation trade-off involves finding the balance between exploring the environment to learn and exploiting the known knowledge to maximize rewards.

8. What does the "discount factor" in RL determine?

The learning rate

The agent's exploration rate

The value of the reward signal over time

The agent's decision-making speed

The discount factor balances the importance of immediate and future rewards.

Explanation

The discount factor balances the importance of immediate and future rewards.

9. What is the action-value function in RL?

The probability of taking an action

The immediate reward of an action

The future reward of an action

The probability of exploring an action

In RL, an agent interacts with an environment by taking actions and receiving feedback in the form of rewards. The goal of the agent is to learn an optimal policy that maps states to actions, maximizing the cumulative rewards over time.
