A Recommendation System is an AI-driven tool

that helps users discover products, services, or
content based on their preferences, behaviors,
or interests. These systems are commonly used

and Spotify to suggest content or products

based on user interactions. Let’s understand

that allows users to upload, view, and share videos. It serves as a hub for entertainment, education,
