Bayesian Networks Fundamentals and Practical Applications

Probabilistic modeling is at the heart of modern decision-making systems, machine learning, and artificial intelligence. This course provides a clear, step-by-step introduction to Bayesian networks, helping you understand how complex probability distributions can be represented and analyzed. You will transition from basic probability concepts to designing and interpreting network structures for real-world scenarios. What you'll learn: Understand foundational concepts of conditional probability and Bayes' theorem; Map variables and dependencies into directed acyclic graphs (DAGs); Calculate joint probability distributions within a network structure; Apply inference techniques to make predictions under uncertainty; Practice identifying d-separation and conditional independence; Explore how Bayesian networks integrate with modern machine learning workflows. We begin with essential definitions and mathematical foundations before moving on to network construction, inference algorithms, and practical modeling scenarios. This course is designed for beginners, data analysts, and software developers looking to build a strong foundation in probabilistic reasoning without any prior experience in graphical models.
