How Does a Recommendation Engine Work? - DZone AI

Shopping is a necessity for every human being. And when we shop, we tend to buy products recommended by people we trust. That's why, in the digital age, any online shop you visit uses some sort of recommendation engine. Recommendation engines are data filtering tools that make use of algorithms and data to recommend the most relevant items to a particular user. In simpler terms, they're nothing but an automated version of a "shop counter guy."
