BayesNet

TikZ library for drawing Bayesian networks, graphical models and (directed) factor graphs in LaTeX.

Contents

Provides the following node styles:

• :code:latent

• :code:obs

• :code:det

• :code:const

• :code:factor

• :code:plate

• :code:gate

Provides the following commands (note that any of the arguments can be empty):

• :code:\factor [options] {name} {caption} {inputs} {outputs}

• :code:\plate [options] {name} {fitlist} {caption}

• :code:\gate [options] {name} {fitlist} {inputs}

• :code:\vgate {name} {fitlist-left} {caption-left} {fitlist-right} {caption-right} {inputs}

• :code:\hgate {name} {fitlist-top} {caption-top} {fitlist-bottom} {caption-bottom} {inputs}

• :code:\edge [options] {inputs} {outputs}

• :code:\factoredge [options] {inputs} {factors} {outputs}

Usage

Install the package by copying tikzlibrarybayesnet.code.tex to your LaTeX system or copy the file into projects that are using it. To use the library in your LaTeX file

.. code-block:: python

\usepackage{tikz} \usetikzlibrary{bayesnet}

Compile the LaTeX example:

.. code-block:: none

pdflatex example.tex

and see the resulting PDF file example.pdf.

Example

This library is derived from a technical report "Directed Factor Graph Notation for Generative Models" and the accompanying TikZ macros by Laura Dietz 2010 (http://people.cs.umass.edu/~dietz/). The technical report is available in this repository as dietz-techreport.pdf.

GraphViz (http://www.graphviz.org/) is a more general open source graph visualization software. It uses DOT file format to describe the structure of the graph. The DOT file can be converted to LaTeX using :code:dot2tex (http://www.fauskes.net/code/dot2tex/).

UAI (http://graphmod.ics.uci.edu/uai08/FileFormat) is a simple text file format to describe Markov networks. The UAI file format can be converted to DOT file format using :code:uai2dot (https://github.com/drewfrank/uai2dot).
