This book points out the deficiencies of uncertainty propagation methods, and describes the most common methods, and illustrates, with examples, the errors that can be made if they are used without due care. Some alternative methods for solving the main problems are given.
Special attention is paid to the learning problem.
Only a few of the existing expert systems have learning capabilities and practically all have only parametric learning possibilities. However, there are many well-developed statistical areas that are very closely related to this problem. Chapters 5 and 6 discuss some of them and open up a wide range of possibilities, such as log-linear, regression, discriminant or causal network models.
