tikz-nef

The nef TikZ library provides predefined styles and shapes to create diagrams for neural networks constructed with the methods of the Neural Engineering Framework (NEF) 1.

The example above was generated with this code:

\begin{tikzpicture}[nef]
    \graph {
        input [ext] -> gate [ens] -> integrator/$x$ [ens] -> output [ext];
        integrator -> [bend right, "$-1$"] gate;
        integrator -> [recurrent] integrator;
        store -> [inhibit] gate;
    };
\end{tikzpicture}

The following styles are supported:

• ea: ensemble array
• ens: ensemble
• ext: external input or output
• inhibt: inhibitory connection
• net: network
• pnode: pass-through node
• rect: rectification ensemble
• recurrent: recurrent connection

Installation

While this package is not available in CTAN follow these instruction:

1. Create the required installation directory (if not already existing): mkdir -p "$(kpsewhich -var-value TEXMFHOME)/tex/generic"
2. cd "$(kpsewhich -var-value TEXMFHOME)/tex/generic"
3. git clone https://github.com/jgosmann/tikz-nef.git
