Add more code examples and outputs.

[igormorgado]

I could not figure out how to use the following parameters:

• \layer -> exclude parameter.
• \link -> from layer, from node, to layer, to node

Can you please add some examples explaining these parameters?

Please add some examples with "dotted" layers as in this TeX exchange answer https://tex.stackexchange.com/a/153974/164318

Found out about exclude and \link parameters. But still not able to do the example with "dotted" elements in a layer (as the link).

Here below there are two examples to share if you wish

Exclude example.

\begin{neuralnetwork}[height=5]
	\newcommand{\nodetextclear}[2]{}
	\setdefaultnodetext{\nodetextclear}
	\inputlayer[count=4, bias=false, title=Input]
	\hiddenlayer[count=5, bias=false, title=Hidden, exclude={3,4}]
	\linklayers[title={$w_{ij}$},not to={3,4}]
	\outputlayer[count=3, title=Output]
	\linklayers[title={$w_{jk}$},not from={3,4}]
\end{neuralnetwork}

Custom links, with nice bezier curves.

\begin{neuralnetwork}[height=6]
	\newcommand{\nodetextclear}[2]{}
	\setdefaultnodetext{\nodetextclear}
	\inputlayer[count=4, bias=false, title=Input]
	\hiddenlayer[count=5, bias=false, title=Hidden]
	\linklayers
	\outputlayer[count=3, title=Output]
	\linklayers
	\link[style={red,dashed, very thick, out=40, in=120}, from layer=0, from node=1, to layer=2, to node=1]
	\link[style={blue,dotted, very thick, out=55, in=40, looseness=1.4}, from layer=0, from node=1, to layer=2, to node=2]
\end{neuralnetwork}

By the way, should be nice, somehow autoadd, not to and not from in the following linklayers when using exclude. Otherwise it leads to vectors pointing to nowhere.

I was able to "customize" the dotted layer with a custom \link, here is an example:

\begin{neuralnetwork}[height=5]
	\newcommand{\nodetextclear}[2]{}
	\setdefaultnodetext{\nodetextclear}
	\inputlayer[count=4, bias=false, title=Input]
	\hiddenlayer[count=5, bias=false, title=Hidden, exclude={3,4}]
	\linklayers[title={not to={3,4}]
	\outputlayer[count=3, title=Output]
	\linklayers[title={not from={3,4}]
	\link[style={-, line width=2mm,line cap=round, dash pattern=on 0pt off 6mm, shorten <= 6mm, shorten >= 4mm}, from layer=1, from node=2, to layer=1, to node=5]
\end{neuralnetwork}

Maybe there is a better way to this.

[igormorgado]

Found a better way for "dots"

\node[below=.25cm of L0-2] {$\vdots$};

where L0-2 is the layer id and node id.

CAVEAT: Excluded layers are not created, hence it needs a "below=" from tikz positioning.
