Designing Recommender Systems with Machine Learning and AI

Personalized recommendations drive engagement across the modern web, from streaming platforms to e-commerce sites. Understanding how to design and implement these algorithmic engines is a crucial skill for any aspiring data scientist or software developer. Through this text-based course, you will transition from understanding core recommendation concepts to writing clean, algorithmic code for real-world scenarios. You will explore how modern systems leverage machine learning and artificial intelligence to predict user preferences and deliver relevant content. What you'll learn: - Understand foundational recommendation concepts, including user-item interactions and explicit versus implicit feedback. - Implement collaborative filtering and content-based filtering methods using clear step-by-step algorithms. - Apply matrix factorization techniques to solve the cold-start problem and handle sparse data. - Explore modern deep learning approaches and vector databases for high-performance similarity searches. - Evaluate recommender system accuracy using industry-standard metrics like precision and recall. The journey begins with basic definitions and historical context before moving systematically through classic algorithms, modern neural approaches, and evaluation strategies. Through structured written lessons and practical code snippets, you will build a solid theoretical and practical foundation. This course is designed for beginners in machine learning and developers who want to understand the mechanics of recommendation systems, with no prior artificial intelligence experience required.
