Designing Recommender Systems with Machine Learning

In a world of infinite choice, personalization is key to keeping users engaged and satisfied. This course guides you through the foundational concepts, mathematical principles, and practical algorithms used to build modern recommender systems. You will transition from understanding basic recommendation concepts to designing, implementing, and evaluating intelligent systems. Through clear written explanations and structured code walk-throughs, you will gain the skills to implement collaborative filtering, content-based systems, and advanced deep learning approaches. What you'll learn: Understand foundational recommendation concepts, user-item interactions, and data preparation techniques; Build collaborative filtering models using matrix factorization and similarity metrics; Develop content-based filtering systems leveraging text processing and item metadata; Apply deep learning architectures, including recurrent neural networks, for sequential recommendation; Implement modern vector database concepts to scale recommendations with embeddings; Evaluate system performance using offline metrics like precision, recall, and NDCG. The journey begins with core terminology and simple similarity measures before advancing to matrix factorization, neural networks, and modern scalability patterns. Each concept is reinforced with practical Python-based code snippets to read, analyze, and apply. This course is designed for aspiring data scientists, software developers, and analytical minds new to recommendation engines; a basic understanding of Python is helpful but no prior machine learning experience is required.
