Questions & Answers

Q: What is machine learning's definition?

Machine learning is the study that gives computers the ability to learn without being exclusively programmed.

Q: How did author Samuel improve the checkers program?

Author Samuel programmed the computer to play tens of thousands of checkers games against itself to learn from winning and losing positions.

Q: What happens if a learning algorithm has played fewer games?

The learning algorithm's performance will be worse since it has had fewer opportunities to learn and improve.

Q: What are the two main types of machine learning algorithms?

The two main types are supervised learning and unsupervised learning.

Summary & Key Takeaways

  • Machine learning is defined as the study that allows computers to learn without being explicitly programmed.

  • Author Samuel developed a checkers program that improved its gameplay by playing thousands of games against itself.

  • There are two main types of machine learning algorithms: supervised learning and unsupervised learning, with supervised learning being the most commonly used.
