\tikzstyle{line} = [draw, -latex']
\begin{tikzpicture}[auto, node distance=1cm,>=latex']
\node [input, name=input] {};
\node [block, below=of input] (nn) {Neural Network};
\node [block, below=of nn] (error) {Cost of the error};
\node [input, right=of error, name=out] {};
\node [block, below=of error] (opt) {Optimiser};
\draw [draw,->] (input) -- node {Input} (nn);
\draw [draw,->] (out) -- node[xshift=1.75cm, yshift=0.3cm] {Actual output} (error) ;
\draw [->] (nn) -- node {Calculated output} (error);
\draw [->] (error) -- (opt);
\end{tikzpicture}
\end{document}
結果は次のとおりです。
しかし、ご覧のとおり、左側の部分がまだ欠落しており、このような方法ではテキスト付きの矢印を作成できませんでした。どうすればよいでしょうか?

あなたは TikZ を初めて使うようですね。シンプルな描画方法を使用することをお勧めします。シンプルな図形はシンプルな方法で描画する必要があります。
\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\tikzset{block/.style={
text=white,
fill=red!70!black,
minimum height=1cm,
minimum width=3cm}}
\begin{tikzpicture}[thick,red!70!black]
\path
(0,0) node[block] (N) {Neural Network}
++(-90:2.5) node[block] (C) {Cost of the error}
+(-90:2) node[block] (O) {Optimizer};
\draw[<-] (N.north)--+(90:.5) node[above,black] {Input};
\draw[->] (N)--(C) node[midway,right,black] {Calculated output};
\draw[<-] (C.east)--+(0:.5) node[right,black] {Actual output};
\draw[->] (C)--(O);
\draw[<-] (N)--++(180:3) coordinate (A)--++(-90:5.5) coordinate (B)-|(O);
\path (A)--(B) node[midway,left,align=left,black] {New weights\\and constants};
\end{tikzpicture}
\end{document}
アップデート1。>=stealth
tikzpicture のオプションとして 矢印を変更できます。Zarko の回答の矢印が最も見栄えが良いようです ^^
\usetikzlibrary{arrows.meta}
\begin{tikzpicture}[thick,red!70!black,>={Straight Barb[angle=60:3pt 2]}]
アップデート2。ライブラリのオプションを覚えていない場合arrows.meta
、ユーザー定義の矢印も便利です。ここでは、という名前の矢印を設計しました。ミーム、シアン色で、 を使用します。このオプションはこの目的に非常に適していることpic
がわかります。[sloped, pos]
\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\tikzset{
block/.style={text=white,
fill=brown,
minimum height=1cm,
minimum width=3cm},
meme/.pic={% my favourite arrow
\draw[teal] (150:6pt)--(0,0)--(-150:6pt);}
}

次のように、コードをできるだけ変更しませんでした。
1) あなたの例と同じ色を得るために、私はStefan Trostの無料のピペットツール: そして、xcolor パッケージで同じ色を定義します:
\usepackage{xcolor}
\definecolor{myred}{RGB}{149, 55, 53}
2) ブロックの最小幅は3 cm
block/.style = {draw, rectangle,fill=myred,text=white,
minimum height=1cm,
minimum width=3cm}
3) ブロックに矢印を描くには(error)
、まずその右側に を配置し、次に構文node
で矢印を描きます。edge
\node[right=of error]{Actual output}edge[->](error);
4) 回り込む矢印には補助線を配置するnode (aux)
% auxiliary node (aux)
\node [coordinate,below left=4mm and 10 mm of opt](aux){};
|-
と構文を使って-|
四角い線を描きます。テキストをposition 0.25
\draw [->](opt)|-(aux)|-node[pos=.25,align=left]{New weigths \\and constant}(nn);
