A Bayesian Network is a graphical model that represents the probabilistic relationships among a set of variables. Coursera's Bayesian Network catalogue teaches you the principles and applications of Bayesian Networks, a crucial component of Artificial Intelligence and Machine Learning. You'll learn about the foundation of probabilistic reasoning, inference and learning algorithms, and how to handle uncertainty in complex systems. You'll also gain experience in constructing probabilistic models, making predictions, and improving decision making under uncertainty. Mastering Bayesian Network prepares you for roles in data analysis, machine learning, AI development, and other fields requiring deep knowledge of statistics and probability.
