What is a recommendation system?
A recommendation system is any system that can predict a preference or a usefulness score given to an item by a user. Using this preference score, it can recommend items to the user.
Items here can be digital products such as movies, music, books, and even clothes. The goal of every recommendation system is to be able to recommend items that the user will like.
Recommendation systems are very popular and can be found almost everywhere; for example:
- Movie streaming platforms such as Netflix, Amazon Prime, Hulu, and Disney+ use recommendation systems for recommending movies to you.
- Social media websites such as Facebook, Twitter, and Instagram use recommendation systems for recommending friends to connect with.
- E-commerce websites such as Amazon and AliExpress use recommendation systems for recommending products such as clothes, books, and electronics.
Recommendation systems are mostly built using data from user-item interaction...
