***NOTE*** CTAN isn't letting me update their copy of the package and I don't have time to waste chasing it. ** The CTAN version is *out of date. ** ** The Github repository has the most up-to-date version. ** Title: Neural Network Author: Mark K Cowan, mark@battlesnake.co.uk Installation: The most up-to-date version of this package is available as a git repository: battlesnake/neural https://github.com/battlesnake/neural This package is also available on CTAN as `neuralnetwork`: /graphics/pgf/contrib/neuralnetwork http://www.ctan.org/tex-archive/graphics/pgf/contrib/neuralnetwork Description: LaTeX package for drawing graphs, particularly neural network diagrams. % Diagram is created via the neuralnetwork environment \begin{neuralnetwork} [nodespacing=10mm, layerspacing=25mm, maintitleheight=2.5em, layertitleheight=2.5em, height=5, toprow=false, nodesize=17pt, style={}, title={}, titlestyle={}] % nodespacing = vertical spacing between nodes % layerspacing = horizontal spacing between layers % maintitleheight = space reserved for main title % layertitleheight = space reserved for layer titles % height = max nodes in any one layer [REQUIRED] % toprow = top row in node space reserved for bias nodes % nodesize = size of nodes % style = style for internal "tikzpicture" environment % titlestyle = style for main title % To customize the text within nodes, define a macro like: \newcommand{\mynodetext}[2] { % layer=#1, node=#2 } % The assign it: \setdefaultnodetext{\mynodetext} % To draw a layer (advanced): \layer[title={}, titlestyle={}, count=5, nodeclass={hidden neuron}, biaspos=top top=false, exclude={}, widetitle=false, bias={}] % title = layer title % titlestyle = style for layer title % count = nodes in this layer (excl. bias node) % nodeclass = class of node: % "neuron", which is base class for: % "input neuron" % "output neuron" % "hidden neuron" % biaspos = position of bias node: % "top" - immediately above other nodes % "top row" - at the top of the node space, in % the area reserved by setting parameter % "toprow = true" on the "neuralnetwork" % environment % "center" - center of layer % "center left" - left of "center" % "center right" - right of "center" % "center left left" - left of "center left" % "center right right" - right of "center right" % top = layer is vertically aligned to the top, not the middle % exclude = one-based indices of nodes to avoid drawing % widetitle = allocate extra horizontal space for layer title % bias = true to add a bias node, false otherwise [REQUIRED] % To draw a layer (simpler): % "\layer" is wrapped up into some simpler macros, which can % accept the same parameters as "\layer" \inputlayer[count=16] % bias=true, nodeclass={input neuron} \hiddenlayer[count=12] % bias=true, nodeclass={hidden neuron} \linklayers \hiddenlayer[count=12] % bias=true, nodeclass={hidden neuron} \linklayers \outputlayer[count=3] % bias=false, nodeclass={output neuron} \linklayers % "\linklayers" links every node in the previous layer to the % layer before it. % To customize the text on the links, define a macro like: \newcommand{\mylinktext}[4] { % from layer=#1, from node=#2 % to layer=#3, to node=#4 } % Then assign it: \setdefaultlinklabel{\mylinktext} % To link the nodes of the previous two layers together: \linklayers[title={}, style={}, not from={}, not to={}] % title = title to put above the links (i.e. between layers) % style = passed to "style" param of "\link" % not from = one-based indices of nodes to NOT link from % not to = one-based indices of nodes to NOT link to % To draw a link from one node to another: \link[style={}, labelpos=midway, from layer, from node, to layer, to node] % style = style for the link path % labelpos = TikZ position of the label node along the path: "midway", "near end", "very near start", "at start", "pos=0.35", etc % from layer = layer to link from [REQUIRED] % from node = node to link from [REQUIRED] % to layer = layer to link to [REQUIRED] % to node = node to link to [REQUIRED] \end{neuralnetwork}
