How does Netflix use reinforcement learning?

You guessed it – they use machine learning. Netflix uses an ML technology called a “recommendation engine” to suggest shows and movies to you and other users. As the name suggests, a recommendation system recommends products and services to users based on available data.

What is a recommendation system in machine learning?
