Bayesian Networks
This page documents all the tools within the dlib library that relate
to the construction and evaluation of Bayesian networks. If you want
a quick introduction to the tools then you should consult the
Bayesian Net example program.
The
library also comes with a graphical application to assist in the
creation of bayesian networks. This application is one of the
example programs, so to use it
you have to compile it yourself.
bayesian_network_join_tree
dlib/bayes_utils.h
dlib/bayes_utils/bayes_utils_abstract.h
This object represents an implementation of the join tree algorithm
(a.k.a. the junction tree algorithm)
for inference in bayesian networks.

bayes_net_from_disk_ex.cpp.html
bayesian_network_gibbs_sampler
dlib/bayes_utils.h
dlib/bayes_utils/bayes_utils_abstract.h
This object performs Markov Chain Monte Carlo sampling of a bayesian
network using the Gibbs sampling technique.

bayes_node
dlib/bayes_utils.h
dlib/bayes_utils/bayes_utils_abstract.h
This object represents a node in a bayesian network. It is
intended to be used inside the directed_graph object to
represent bayesian networks.

conditional_probability_table
dlib/bayes_utils.h
dlib/bayes_utils/bayes_utils_abstract.h
This object represents a conditional probability table.
joint_probability_table
dlib/bayes_utils.h
dlib/bayes_utils/bayes_utils_abstract.h
This object represents a joint probability table.
assignment
dlib/bayes_utils.h
dlib/bayes_utils/bayes_utils_abstract.h
This object models an assignment of random variables to particular values.
It is used with the joint_probability_table and
conditional_probability_table
objects to represent assignments of various random variables to actual values.
