Definition
Recommendation systems use AI to suggest products, content, or connections based on user behavior and preferences.
How It Works
AI analyzes what you've liked, bought, or viewed, then finds patterns with similar users. If people who like sci-fi movies also enjoy certain books, the system suggests those books to other sci-fi fans.
Some systems focus on item similarities, others on user similarities, and many combine both approaches.
Why It Matters
Recommendations drive much of the modern internet economy. Netflix suggests shows, Amazon suggests products, Spotify suggests music, and LinkedIn suggests connections.
Good recommendations keep users engaged and help them discover relevant content they might miss otherwise.
