Bayesian Networks, the result of the convergence of artificial
intelligence with statistics, are growing in popularity. Their versatility and modelling
power is now employed across a variety of fields for the purposes of analysis, simulation,
prediction and diagnosis.
This book provides a general introduction to Bayesian networks, defining
and illustrating the basic concepts with pedagogical examples and twenty real-life case
studies drawn from a range of fields including medicine, computing, natural sciences and
engineering.
Designed to help analysts, engineers, scientists and professionals taking part
in complex decision processes to successfully implement Bayesian networks, this book
equips readers with proven methods to generate, calibrate, evaluate and validate Bayesian
networks.
The book:
- Provides the tools to overcome common practical challenges such as the treatment
of missing input data, interaction with experts and decision makers, determination of the
optimal granularity and size of the model.
- Highlights the strengths of Bayesian networks whilst also presenting a
discussion of their limitations.
- Compares Bayesian networks with other modelling techniques such as neural
networks, fuzzy logic and fault trees.
- Describes, for ease of comparison, the main features of the major Bayesian
network software packages: Netica, Hugin, Elvira and Discoverer, from the point of view of
the user.
- Offers a historical perspective on the subject and analyses future directions
for research.
Written by leading experts with practical experience of applying Bayesian
networks in finance, banking, medicine, robotics, civil engineering, geology, geography,
genetics, forensic science, ecology, and industry, the book has much to offer both
practitioners and researchers involved in statistical analysis or modelling in any of
these fields.
Olivier Pourret is a research engineer at Électricité de France
(EDF) and an analyst at EDF Trading. He has published a number of papers describing his
use of Bayesian Belief Networks (BBNs), and co-authors a book on the subject. He also
taught reliability modeling at the University of Marne-la-Vallée from 1998 to 2002, and
initiated the BBN course at EDF R&D Training Institute in 1999.
Patrick Naim is the founder and CEO of Elsewhere, an engineering company
specialized in knowledge technologies and quantitative modeling. He also works as a
consultant in operational risk modeling for a major French bank, and in design risk
modeling for a major US oil company. He is the author or co-author of four books (2 Wiley
titles) in data mining, data modeling and BBNs, and he teaches data modeling and Bayesian
networks at three Parisian schools.
Bruce Marcot is a research wildlife ecologist with the Ecosystems Processes
Research Program in the US. He conducts applied scientific research and technology
application projects for risk assessment and decision modeling in forest resource and
wildlife planning. Author of several papers on the use of BBNs, he is sought for lecturing
and teaching short courses on BBN and decision modeling methods.
