This is the first textbook on pattern recognition to present the
Bayesian viewpoint. The book presents approximate inference algorithms
that permit fast approximate answers in situations where exact answers
are not feasible. It uses graphical models to describe probability
distributions when no other books apply graphical models to machine
learning. No previous knowledge of pattern recognition or machine
learning concepts is assumed. Familiarity with multivariate calculus and
basic linear algebra is required, and some experience in the use of
probabilities would be helpful though not essential as the book includes
a self-contained introduction to basic probability theory.
