In this lesson, you’ll create an Interaction Model that tracks user actions, like voting, viewing, or asking questions. This model is essential for understanding how users engage with your platform and helps in building recommendation algorithms to provide personalized experiences. ### Why Do We Need an Interaction Model? 🤔 Imagine a user interacts with multiple pieces of content on your platform. They might upvote a few answers, view several questions, or even ask a question themselves. By tracking these interactions, you can build an intelligent recommendation algorithm that suggests content based on user behavior.
