What are Recommender Systems?
Recommender Systems are a type of AI that is used to predict what a user might like based on their interests, preferences, and historical data. The recommendation engine is personalized for the user, making suggestions that are not just based on similar tastes but also connections and social context. Recommendations include posts, products, or anything that the user might be interested in. There are many different types of recommender systems including: collaborative filtering, content-based filtering, collaborative association rule learning (often referred to. as content-based recommendations), item-based collaborative filtering, and conversational agents. Collaborative Filtering: Collaborative filtering is a recommender system that uses algorithms to predict the ratings or preferences of items by looking at the ratings of other users who have similar tastes. Collaborative filtering looks at users who are similar to the user being recommended and uses these users’ ratings to predict or rank the item in question.

Recommender systems can be found in many different industries such as e-commerce, entertainment and more. They are used to recommend products or content to users by predicting what they might like based on past actions or behaviors. For example, a user who has purchased multiple books from Amazon might be recommended The Hunger Games, Mobile recommendation apps are rising in popularity with the ever more connected world. Mobile apps like Swiggy can recommend restaurants on their previous purchases. Online music stores such as Amazon, iTunes and Google Play can recommend songs based on the user’s past purchases. Music recommendation algorithms will also look at trends in new releases for the genre that a user is interested in, what other artists are releasing who are of similar style and popularity with similar users, along with other data points to create a list of potential recommendations. Recommendation systems are often used in the emerging field of collaborative filtering. Collaborative filters recommend options based on the choices and preferences of others in a similar situation. The recommendation is then adjusted as more information is collected. If the first recommendation was to purchase a red shirt, then as more purchases are made, it can be adjusted to show green shirts or blue shirts.
