Building Recommender Systems with Deep Learning: An Applied Approach

In a world flooded with digital content, delivering the right product or recommendation to the right user at the right time is a superpower for any application. This written course guides you step-by-step through the process of building intelligent recommendation engines using modern deep learning techniques. You will transition from understanding basic recommendation concepts to implementing neural architectures that power real-world personalization. By studying clear written explanations and analyzing practical code implementations, you will learn how to handle sparse data, build neural collaborative filtering models, and leverage vector search for high-performance retrieval. What you will learn: Understand the core terminology, paradigms, and mathematical foundations of recommendation systems; Build collaborative filtering and content-based recommendation models using neural networks; Implement modern two-tower neural architectures for efficient retrieval and ranking; Apply vector search concepts and index representations to scale your recommendations; Evaluate your models using industry-standard offline metrics such as precision, recall, and NDCG; Configure basic MLOps principles to monitor and update recommendation models safely. The course begins with foundational definitions and classic recommendation strategies before transitioning into deep learning architectures, modern vector databases, and evaluation frameworks. You will work through structured text-based lessons, conceptual breakdowns, and step-by-step code walkthroughs. This course is designed for aspiring data scientists, software engineers, and curious developers who want a beginner-friendly path into deep learning-based personalization, with no prior recommender systems experience required.
