An artificial intelligence recommendation system is a type of machine learning technique that allows developers to forecast users’ decisions and provide suitable recommendations.

Users receive tailored service support through recommender systems, which learn their previous habits and forecast their current preferences for certain products. Artificial intelligence (AI), specifically computational intelligence and machine learning methodologies and algorithms, has been used to construct recommender systems to improve prediction accuracy and tackle data sparsity and cold start difficulties.

Amazon’s use of a suggestion engine is exemplified by its “Customer who bought shirt item also bought pants” feature. In general, the content recommendation engine functions as a smart and experienced salesperson who understands the user’s needs, tastes, and requirements and is capable of making informed decisions about recommendations that are beneficial and relevant to the client’s desires, thereby increasing the conversion rate.

How a Recommendation system Work?

The recommender function, which evaluates specific information about the user and forecasts the rating that the user would award to a product, is one of the most important components behind the operation of a product recommendation engine.

A recommendation engine typically goes through the following four stages while processing data:


Page views, order history/return history, and cart events are all examples of data collected here, which can be either explicit or implicit.


The sort of data you use to generate recommendations can assist you choose between NoSQL databases, traditional SQL databases, and object storage.


By filtering user engagement data using multiple analytical methods such as batch analysis, real-time analysis, or near-real-time system analysis, the recommender system examines and discovers items with similar user engagement data


The final stage is to filter the data in order to extract the information needed to make suggestions to the user.

Types of Recommendation Systems

The most popular types of recommendation systems are content based and collaborative filtering.

Content based

Content-based recommender systems produce particular recommendations based on objects or user metadata. The user’s previous purchases are scrutinized. For example, if a user has previously read a book by a particular author or purchased a product from a particular brand, it is considered that the user has a preference for that author or brand and is likely to purchase a similar product in the future.

Collaborative filtering

Collaborative filtering works on the simple principle of using user group behavior to provide suggestions to other users. The advice is referred to as collaborative because it is based on the preferences of other users.
