Netflix’s recommendation algorithms are some of the most famous and successful machine learning models in the entertainment industry. The algorithms help the streaming service to suggest personalized content based on the users' viewing history, ratings, and search history. In this article, we will explain how Netflix‘s recommendation algorithms work.
Netflix uses a combination of Machine Learning algorithms and human curation to suggest content to its users. The primary algorithm used is the collaborative filtering algorithm. Collaborative filtering predicts what a user might like based on the preferences of other users who have similar viewing histories.
When a user watches a movie or TV show, the platform records the viewing history and any associated ratings. Based on this data, Netflix creates a profile of the user’s viewing habits to suggest other titles.
Netflix uses a content-based filtering algorithm, which suggests content based on the attributes of the content itself. If a user watches a comedy, the platform will suggest other titles based on similar themes, actors or directors.
Netflix also takes into factors like the time of day, day of the week, and user’s location. For example, if a user watches a lot of romance on weekend evenings, more romance titles will be suggested during that time window on future weekends.
What else do they use?
In addition to machine learning algorithms, Netflix also employs human curation. A team of editors watches and categorizes movies and TV shows based on genre, mood, and theme. Furthermore, they provide feedback to the algorithm, helping it to refine the generated recommendations.
To ensure that the algorithm is continually learning and improving, Netflix regularly updates it. This involves training the algorithm on new data, adjusting the weighting of different factors, and tweaking the algorithm’s parameters to improve its accuracy.
Netflix’s recommendation algorithm is a complex and sophisticated machine learning model that is continually evolving. By combining collaborative filtering, content-based filtering, and human curation, the subscription-based streaming service is able to suggest personalized content to its users based on their viewing habits, preferences, and context. This helps to keep users engaged and ensures that they continue to discover new content that they will love.
