Content-based Recommender System with Python

What are recommender systems

  • Recommender systems are methods that predict users’ interests and make meaningful recommendations to them for different items, such as songs to play on Spotify, movies to watch on Netflix, news to read about your favourite newspaper website or  products to purchase on Amazon.

Types of recommender systems

  • Content-based recommenders rely on attributes of users and/or items, whereas collaborative filtering uses information on the interaction between users and items, expressed in the so-called user-item interaction matrix.
