How to Build a Recommendation System in Python?.How to Build a Recommendation System in Python: Table of Contents Then, I will walk you through how to build an end-to-end content-based recommendation system in Python. In this article, I will briefly explain the different types of recommendation systems and how they work. Almost every mid to large-sized organization that sells a variety of services online uses some type of automated system to make product suggestions to customers, and there is a high demand for experts who can oversee this process. If you would like to work as an analyst or marketing data scientist at companies like Netflix, Amazon, Uber, and Spotify, it is a good idea to learn how recommender systems work and even build one yourself. This is a powerful technique employed by service providers and subscription platforms to keep you on the site and prevent you from moving to a competitor’s product. Recommendation systems are able to predict your interest in an item even before you are aware of it. This is because the platform’s recommendation system has analyzed your streaming behavior in relation to other users, and is able to predict that you might find a particular show interesting.

You might have received movie recommendations on Netflix that were completely unrelated to the content you usually watch. This way, not only will you be given recommendations based on your activities on the site, but your profile is also compared with that of other users to predict what you might like.įor example, if you are new to Netflix and only signed up because of three action movies you wanted to watch, the platform will try to get you interested in other genres so that they don’t lose you as a customer. Due to this, recommendation systems can be created on data points collected from millions of users. Nowadays, organizations have the ability to track data on a much larger scale than they did just two years ago. The user experience can get so personalized that the algorithm will even be able to predict the type of music you will enjoy during different times of the day. As you continue listening to music that you enjoy, your recommendations become more accurate. You will initially be recommended the most popular songs on the app since this music appeals to a wide audience. These algorithms come up with personalized content suggestions that improve over time as you continue to spend time on the platform.įor instance, notice how music recommendations on Spotify are generic at first. Recommendation systems, commonly referred to as recommender systems, are a popular application of data science in marketing.Ĭompanies like Amazon, Netflix, and Spotify use recommendation systems to enhance user experience on their platforms. Have you ever watched a movie on Netflix, only for the platform to suggest movies of the same genre, starring similar cast members? This is an example of a recommendation system.
