What is Recommendation Engine?
A recommendation engine uses algorithms to suggest relevant products, content, or actions to users.
Definition
Recommendation engines analyze user behavior and preferences to predict what they will want next. Types include collaborative filtering (users like you also liked), content-based (similar to what you liked), and hybrid approaches. They drive significant revenue in e-commerce and engagement in content platforms.
