  • Behavior Tracking: Track user interactions and behavior (e.g., clicks, purchases, ratings).
• Collaborative Filtering Algorithm:
  • User-Based Collaborative Filtering: Implement algorithms that recommend items based on the preferences of similar users.
  • Item-Based Collaborative Filtering: Implement algorithms that recommend items similar to those a user has liked in the past.
  • Matrix Factorization: Use techniques like Singular Value Decomposition (SVD) for improved recommendation accuracy.
• Recommendation Engine:
  • Recommendation Generation: Generate personalized recommendations based on user profiles and collaborative filtering algorithms.
  • Real-Time Recommendations: Provide real-time recommendations as users interact with the system.
  • Hybrid Approaches: Integrate collaborative filtering with other recommendation techniques (e.g., content-based filtering) for better performance.
• User Interface Module:
  • Recommendation Display: Present recommendations in an intuitive and engaging manner.
  • Feedback Mechanism: Allow users to provide feedback on recommendations to improve the system.
  • User Profile Management: Enable users to view and edit their profiles and preferences.
• Performance Evaluation Module:
  • Accuracy Metrics: Measure recommendation accuracy using metrics like Precision, Recall, F1-Score, and Mean Absolute Error (MAE).
  • User Satisfaction: Assess user satisfaction through surveys or feedback forms.
  • System Performance: Evaluate system performance in terms of response time and scalability.

4. Technology Stack

• Programming Languages: Languages for implementing algorithms and system logic (e.g., Python, Java).
• Frameworks and Libraries: Libraries for machine learning and data processing (e.g., Scikit-Learn, TensorFlow, NumPy).
• Database: Technologies for storing user data and item information (e.g., SQL databases, NoSQL databases).
• Frontend Technologies: Technologies for developing the user interface (e.g., HTML/CSS, JavaScript, React).
• Backend Technologies: Technologies for server-side development (e.g., Node.js, Django, Flask).

5. Implementation Plan
