BayesNet

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

Contents

Provides the following node styles:

• latent
• obs
• det
• const
• factor
• plate
• gate

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

• \factor [options] {name} {caption} {inputs} {outputs}
• \plate [options] {name} {fitlist} {caption}
• \gate [options] {name} {fitlist} {inputs}
• \vgate {name} {fitlist-left} {caption-left} {fitlist-right} {caption-right} {inputs}
• \hgate {name} {fitlist-top} {caption-top} {fitlist-bottom} {caption-bottom} {inputs}
• \edge [options] {inputs} {outputs}
• \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

\usepackage{tikz}
\usetikzlibrary{bayesnet}

Compile the LaTeX example:

pdflatex example.tex

and see the resulting PDF file example.pdf.

Example

PCA model as a Bayesian network and a directed factor graph.

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 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 uai2dot (https://github.com/drewfrank/uai2dot).
