Question

你能帮忙画一下上面的图吗？

这是我迄今为止尝试过的代码：

\documentclass{article}
\usepackage{tikz}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{calc,shapes, positioning}
\usetikzlibrary{arrows}
\usetikzlibrary{decorations.text}
\usetikzlibrary{matrix,chains,positioning,decorations.pathreplacing,arrows}

\begin{document}


\begin{tikzpicture}[
init/.style={
    draw,
    circle,
    inner sep=2pt,
    font=\Huge,
    join = by -latex
},
squa/.style={
    draw,
    inner sep=2pt,
    font=\Large,
    join = by -latex
},
start chain=2,node distance=13mm
]

\node[on chain=2,init] (sigma) 
    {$\displaystyle\Sigma$};
\node[on chain=2,squa,label=above:{\parbox{2cm}}]   
    {$+$};
\node[on chain=2,squa,label=above:,join=by -latex] 
    {$y$};

\node[label=above:\parbox{2cm}{\centering Bias \\ $$}] at (sigma|-w1) (b) {};

\end{tikzpicture}

\end{document}
