Description
A general framework for constructing and the usage of probabilistic models of complex systems that would enable a pc to use available information for making decisions.
Most tasks require a person or an automated system to reason — to reach conclusions based on available information. The framework of probabilistic graphical models, presented in this book, provides a general approach for this task. The approach is model-based, allowing interpretable models to be constructed and then manipulated by reasoning algorithms. These models can be learned automatically from data, allowing the approach to be used in cases where manually constructing a model is difficult or even not possible. Because uncertainty is an inescapable aspect of most real-world applications, the book makes a speciality of probabilistic models, which make the uncertainty explicit and provide models that are more faithful to reality.
Probabilistic Graphical Models discusses quite a few models, spanning Bayesian networks, undirected Markov networks, discrete and continuous models, and extensions to take care of dynamical systems and relational data. For each class of models, the text describes the three fundamental cornerstones: representation, inference, and learning, presenting both basic concepts and advanced techniques. In spite of everything, the book considers using the proposed framework for causal reasoning and decision making under uncertainty. The main text in each chapter provides the detailed technical development of the key ideas. Most chapters also include boxes with additional material: skill boxes, which describe techniques; case study boxes, which discuss empirical cases related to the approach described in the text, including applications in computer vision, robotics, natural language understanding, and computational biology; and concept boxes, which present significant concepts drawn from the material in the chapter. Instructors (and readers) can group chapters in quite a lot of combinations, from core topics to more technically advanced material, to suit their particular needs.
