我知道这里已经有一些关于绘制神经网络的问题，但我正尝试绘制类似这样的内容：
我尝试应用一些教程并进行了一些修改，但这是我的结果，它与上面的结果仍然相差甚远。
这是我的代码：
\usepackage{tikz}
\usetikzlibrary{matrix,chains,positioning,decorations.pathreplacing,arrows}
\begin{document}
\def\layersep{5cm}
\begin{tikzpicture}[shorten >=1pt,->,draw=black!50, node distance=\layersep]
\tikzstyle{every pin edge}=[<-,shorten <=1pt]
\tikzstyle{neuron}=[circle,fill=black!25,minimum size=25pt,inner sep=0pt]
\tikzstyle{Cauche d'entrée}=[neuron, fill=gray!33];
\tikzstyle{Cauche cachée}=[neuron, fill=gray!66];
\tikzstyle{Cauche de sortie}=[neuron, fill=gray!99];
\tikzstyle{annot} = [text width=6em, text centered]
% Draw the rectangle
\filldraw[fill=gray!33!white, draw=black] (0,0) rectangle (1.4,6);
% Draw the input layer nodes
\foreach \name / \y in {1,2,3,4,5,6}
% This is the same as writing \foreach \name / \y in {1/1,2/2,3/3,4/4}
\node[Cauche d'entrée] (I-\name) at (0,-\y) {};
% Draw the hidden layer nodes
\foreach \name / \y in {1,2,3,4}
\path[yshift=0.5cm]
node[Cauche cachée] (H-\name) at (\layersep,-\y cm) {};
% Draw the output layer node
\node[Cauche de sortie, pin={[pin edge={->}]right:Prévision}, right of=H-3] (O) {};
% Connect every node in the input layer with every node in the
% hidden layer.
\foreach \source in {1,...,6}
\foreach \dest in {1,2,3,4}
\path (I-\source) edge (H-\dest);
% Connect every node in the hidden layer with the output layer
\foreach \source in {1,...,4}
\path (H-\source) edge (O);
% Annotate the layers
\node[annot,above of=H-1, node distance=1cm] (hl) {Cauche cachée};
\node[annot,left of=hl] {Cauche d'entrée};
\node[annot,right of=hl] {Cauche de sortie};
\end{tikzpicture}
\end{document}
正如你所见，我离我想要画的东西还很远。任何帮助或建议都会很感激。

我尝试重现显示的图像......但图像中可能缺少某些元素，例如输入端的文本等。添加到代码中这应该不是什么大问题:)
请注意，以上姆韦使用最新的tikz语法，而不是过时的语法，因为它在你的姆韦。
