从回答我之前的问题, 我有这个:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes}
\usetikzlibrary{positioning}
\begin{document}
\pagestyle{empty}
\def\layersep{2.5cm}
\begin{tikzpicture}[
shorten >=1pt,->,draw=black!50, node distance=\layersep,
every pin edge/.style={<-,shorten <=1pt},
neuron/.style={circle split,fill=black!25,minimum size=17pt,inner sep=0pt},
input neuron/.style={neuron, fill=green!50},
output neuron/.style={neuron, fill=red!50},
compute neuron/.style={neuron, fill=blue!50},
annot/.style={text width=4em, text centered}
]
% Draw the input layer nodes
\foreach \name / \y in {1,...,4}
% This is the same as writing \foreach \name / \y in {1/1,2/2,3/3,4/4}
\node[input neuron, pin position=-90, rotate=90] (I-\name) at (0,-\y) {};
\node[left=1pt of I-1]{$h_0$};
% Draw the compute layer nodes
\foreach \name / \y in {1,...,5}
\path[yshift=0.5cm]
node[compute neuron,rotate=90] (C-\name) at (\layersep,-\y cm) {};
% Draw the output layer node
\node[output neuron,pin={[pin edge={->}]right:Output}, right of=C-3,rotate=90] (O) {};
% Connect every node in the input layer with every node in the
% compute layer.
\foreach \source in {1,...,4}
\foreach \dest in {1,...,5}
\path (I-\source) edge (C-\dest);
% Connect every node in the compute layer with the output layer
\foreach \source in {1,...,5}
\path (C-\source) edge (O);
% Annotate the layers
\node[annot,above of=C-1, node distance=1cm] (hl) {compute layer};
\node[annot,left of=hl] {Input layer};
\node[annot,right of=hl] {Compute layer};
\end{tikzpicture}
% End of code
\end{document}
注意 $h_0$ 标签的问题。我希望该标签位于节点左侧。我希望其他标签位于节点上方。我该如何实现?节点旋转以适应垂直线似乎会影响标签,但我需要两者。
答案1
像这样?
仍然部分基于猜测,但无论如何。生成上述图像的 MWE 基于我的答案在这里:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}
\newcommand\ppbb{path picture bounding box}
\begin{document}
\pagestyle{empty}
\def\layersep{2.5cm}
\begin{tikzpicture}[shorten >=1pt, ->, draw=black!50,
node distance = \layersep,
every pin edge/.style = {<-, shorten <=1pt},
every label/.style = {label distance=0pt, inner sep=1pt,font=\small},
neuron/.style = {circle, minimum size=17pt, inner sep=0pt,
path picture={%
\path[draw=black!75,semithick,-] (\ppbb.north) -- (\ppbb.south);},
},
input neuron/.style = {neuron, fill=green!50},
output neuron/.style = {neuron, fill=red!50},
compute neuron/.style = {neuron, fill=blue!50},
annot/.style = {text width=4em, text centered},
]
% Draw the input layer nodes
\foreach \y [count=\yi from 0] in {1,...,4}
{\ifnum\y=1
\node[input neuron, label=left:$h_\yi$] (I-\y) at (0,-\y) {};
\else
\node[input neuron, label=$h_\yi$] (I-\y) at (0,-\y) {};
\fi
}
% Draw the compute layer nodes
\foreach \y [count=\yi from 0] in {1,...,5}
\node[yshift=0.5cm,compute neuron,label=$C_\yi$] (C-\y) at (\layersep,-\y cm) {};
% Draw the output layer node
\node[output neuron,pin={[pin edge={->}]right:Output}, right=of C-3.west] (O) {};
% Connect every node in the input layer with every node in the
% compute layer.
\foreach \source in {1,...,4}
\foreach \dest in {1,...,5}
\path (I-\source) edge (C-\dest);
% Connect every node in the compute layer with the output layer
\foreach \source in {1,...,5}
\path (C-\source) edge (O);
% Annotate the layers
\begin{scope}[node distance=0pt]
\node[annot,above=4mm of C-1] (hl) {Compute layer};
\node[annot,above=of hl.south -| I-1] {Input layer};
\node[annot,above=of hl.south -| O] {Output layer};
\end{scope}
\end{tikzpicture}
% End of code
