An example of the former is, “Fred must be in either the museum or the café. In this article, we will study what uncertainty is , how it is related to Artificial Intelligence, and how it affects the knowledge and learning process of an Agent? Though there are various types of uncertainty in various aspects of a reasoning system, the "reasoning with uncertainty" (or "reasoning under uncertainty") research in AI has been focused on the uncertainty of truth value, that is, to allow and process truth values other than "true" and "false". Also, you will learn about a standard algorithm for performing inference called 'belief propagation'. Furthermore, by using a Bayesian network model, we can preserve all the uncertainty that exists in our collective knowledge and perform inference by consciously taking into account all the uncertainty.

The process by which a conclusion is inferred from multiple observations is called inductive reasoning. Relying only on its sensors, an autonomous vehicle has to decide wether to issue an emergency breaking or not. The primitives in probabilistic reasoning are random variables. This book presents an approach to reasoning about uncertainty. The student knows, understands and is able to apply the graphical model approach for dealing with uncertainty; they are familiar with the key concepts and algorithms underlying graphical models such as Bayesian networks (directed graphical models), Markov networks (Markov random field, undirected graphical model), Factor graphs, and Hidden Markov models such as modelling, inference and learning. Depending on the available evidence and on the direction of reasoning within the network, we will look at how inference is performed in this slightly more complex setup. (A).
