Recommender system

A recommender system is like having a friend who knows a lot about a particular topic and can help you find what you're looking for. It works by looking at what other people like you (with similar interests) have liked or liked in the past and then recommending things that those people have already enjoyed. So for example, if you like a certain type of movie, a recommender system might suggest other movies that people who have seen and liked the same movie as you have also enjoyed. This way, you don't have to search through all the movies on your own but can find something that other people who have similar tastes have found interesting.
