1 Extremely technical book
Too synthetic and technical to be used as an introduction to the subject, even for experienced statisticians and graduate students.
2 A comprehensive advanced study book for graduate students
This book starts with basic probabilistic concepts, graph theory, junction trees, conditional independence, to advanced topics related to learning Bayesian network. Many practical examples are clear and helpful. Good for graduate students of computer science and statistics.
