Latex 中的神经网络

Question

我是 Latex 新手，想为我的论文背景部分绘制这些图表。可以获取快照，但看起来不太好。任何帮助都将不胜感激。

Answer 1

这是第一个的起点：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc}

\tikzset{
  redondo/.style={
    draw=blue,
    line width=1pt,
    rounded corners=3pt,
    text width=#1
  },
  punto/.style={
    fill=red,
    circle,
    inner sep=1.25pt
  },
  tresp/.pic={
    \node[punto] at (0.25,0) {};
    \node[punto] at (0.5,0) {};
    \node[punto] at (0.75,0) {};
  },
  dosp/.pic={
    \node[punto] at (0.25,0) {};
    \node[punto] at (0.5,0) {};
  },
  cuadra/.style={
    fill=teal,
    minimum size=10pt
  },
  arr/.style={
    line width=1pt,
    draw=green!70!black,
    ->,
    >=latex
  }  
}

\begin{document}

\begin{tikzpicture}[node distance=2cm and 1cm]
\node[redondo=7cm]
  (upper)
  {};
\pic at (upper.west) {tresp};
\pic at (upper.center) {dosp};
\pic at ([xshift=-1cm]upper.east) {tresp};
\node[] 
  at ([yshift=-1pt]$ (upper.center)!0.5!(upper.west) $ ) {$\ldots$};
\node[] 
  at ([yshift=-1pt]$ (upper.center)!0.5!(upper.east) $ ) {$\ldots$};

\node[redondo=5cm,below=of upper]
  (middle)
  {};
\pic at (middle.west) {tresp};
\pic at ([xshift=-0.75cm]middle.east) {dosp};
\node[] at ([xshift=4pt,yshift=-1pt]middle) {$\ldots$};

\node[redondo=2cm,below=of middle,anchor=east,xshift=-30pt,label={20:$C(w_{t-n+1})$}]
  (lowermiddle)
  {};
\node[redondo=2cm,below=of middle,anchor=west,xshift=30pt,label={10:$C(w_{t-n+1})$}]
  (lowerright)
  {};
\node[redondo=2cm,left=of lowermiddle,label={above left:$C(w_{t-n+1})$}]
  (lowerleft)
  {};

\foreach \Valor/\NodeLabel in {left/n+1,middle/2,right/1/}
{
  \pic at (lower\Valor.west) {tresp};
  \pic at ([xshift=-0.75cm]lower\Valor.east) {dosp};
  \node[cuadra,below=of lower\Valor,label={below:{index for $w_{t-\NodeLabel}$}}] (cuadra\Valor) {};
  \node[] at ([xshift=4pt,yshift=-1pt]lower\Valor) {$\ldots$};
}

\draw[arr,dashed] 
  (lowerleft) to[out=92,in=210] ([xshift=10pt]upper.south west);
\draw[arr,dashed] 
  (lowermiddle) to[out=150,in=210] ([xshift=-50pt]upper.south);
\draw[arr,dashed] 
  (lowerright) to[out=30,in=-30] ([xshift=50pt]upper.south);
\foreach \Valor in {left,middle,right}
{
    \draw[arr] (cuadra\Valor) -- coordinate (aux\Valor) (lower\Valor);
}
\foreach \Valor/\Angulo in {left/186,middle/193,right/350}
{
    \draw[arr] (lower\Valor) -- (middle.\Angulo);
}
\draw[arr] (middle) -- (upper);
\draw[arr] 
  (upper) -- 
  ++(0pt,1cm) node[above] {$i-$th output};
\draw[<->,magenta,dashed,>=latex]
  (auxleft) -- 
  ++(20pt,-10pt) --
  ([shift={(-20pt,-10pt)}]auxright) coordinate[pos=0.5] (auxc) --
  (auxright);
\draw[->,magenta,dashed,>=latex]
  (auxc) -- (auxmiddle);
\node[anchor=south west] 
  at (auxc) {Matrix $C$};    
\node[anchor=north west,align=left] 
  at (auxc) {shared parameters \\ across words};    
\end{tikzpicture}

\end{document}

第二个；用这个你可以轻松创建剩下的一个：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,arrows.meta,calc}

\tikzset{
  arro/.style={
    ->,
    >=latex
  },
  bloque/.style={
    draw,
    minimum height=1cm,
    minimum width=0.5cm
  }  
}

\begin{document}

\begin{tikzpicture}
\node[]
  (input)
  {Input};
\node[bloque,below=of input,label={left:$w(t-2)$}]
  (inputi)
  {};
\node[bloque,below=of inputi,label={left:$w(t-1)$}]
  (inputii)
  {};
\coordinate[below=of inputii] (aux);  
\node[bloque,below=of aux,label={left:$w(t+1)$}]
  (inputiii)
  {};
\node[bloque,below=of inputiii,label={left:$w(t+2)$}]
  (inputiv)
  {};

\node[right=of input]
  (proje)
  {Projection};
\node[bloque,label={above:\textsc{sum}}]
  at (proje|-aux)
  (projei)
  {};

\node[right=of proje]
  (out)
  {Output};
\node[bloque,label={right:$w(t)$}]
  at (out|-aux)
  (outi)
  {};

\foreach \Valor in {i,ii,iii,iv}
{
  \draw[arro] (input\Valor) -- (projei);
}  
\draw[arro] (projei) -- (outi);
\end{tikzpicture}

\end{document}
