Fine-Tuning Conditional Probability Tables in Bayesian Networks

Building accurate Bayesian networks requires more than just feeding raw data into an algorithm; automated learning often introduces errors or fails to capture rare, critical scenarios. This text-only course teaches you how to bridge the gap between automated data learning and human expertise by manually adjusting Conditional Probability Tables (CPTs). You will learn how to inject domain knowledge directly into your probabilistic models to improve decision-making accuracy. What you'll learn: Understand the core mathematical foundations of Bayesian networks and conditional probability; Identify common learning errors and structural anomalies in automated probability tables; Apply expert elicitation techniques to translate human knowledge into precise probability values; Configure and modify CPTs programmatically using modern Python libraries; Validate and test your adjusted networks to ensure overall model consistency and prevent unintended propagation errors. Starting with essential probability definitions and network structures, this course guides you step-by-step through practical refinement workflows using clean Python code snippets. This course is designed for data analysts, aspiring machine learning engineers, and researchers who have a basic understanding of Python and want to master probabilistic reasoning.
