Questions & Answers

Q: What is reinforcement learning?

Reinforcement learning is the study of how an agent interacts with its environment to maximize rewards by taking actions and receiving observations and a reward signal.

Q: What are the common building blocks in reinforcement learning?

The common building blocks in reinforcement learning are the value function (predicting future rewards), policy (decision-making process), and model (predicting future events in the environment).

Q: What is deep reinforcement learning?

Deep reinforcement learning is a family of solution methods that utilizes neural networks to represent the value function, policy, and model, offering a flexible and powerful toolkit for representation and learning.

Q: Why is learning required in reinforcement learning?

Learning is required in reinforcement learning because it is the only way to achieve good performance in complex environments, allowing the agent to continuously improve its actions based on experience.

Q: What is reinforcement learning?
