[Tex/LaTex] The TeX workflow in LaTeX

diagrams

I want to draw TeX work flow, but I don't know how to start, any help please?

This is from an example provided to my students in a LaTeX class (circa 2010-2014)

\documentclass{article}
%\usepackage[margin=1in]{geometry}
%\usepackage[latin1]{inputenc}
\usepackage{tikz}  
\usetikzlibrary{shapes,arrows}
\begin{document}  

% Define block styles
\tikzstyle{decision} = [diamond, draw, fill=blue!20, 
    text width=4.5em, text badly centered, node distance=3cm, inner sep=0pt]
\tikzstyle{block} = [rectangle, draw, fill=blue!20, 
    text width=5em, text centered, rounded corners, minimum height=4em]
\tikzstyle{blockred} = [rectangle, draw, fill=red!20, 
    text width=5em, text centered, rounded corners, minimum height=4em]
\tikzstyle{line} = [draw, -latex']
\tikzstyle{cloud} = [draw, ellipse,fill=red!20, node distance=3cm,
    minimum height=2em]

\begin{tikzpicture}[node distance = 2cm, auto]
% Place nodes
    \node [block] (edit) {Edit source with \TeX{}maker};
    \node [blockred, above of=edit] (setup) {Setup for document};
    \node [block, right of=edit, node distance=3cm] (compile) {Compile source};
    \node [block, below of=compile, node distance=3cm] (view) {View output};
    \node [decision, below of=view, node distance=3cm] (decide) {Ready to Print?};
    \node [blockred, right of=decide, node distance=5cm] (print) {Print document};

    \path [line,dashed] (setup) -- (edit);
    \path [line] (edit) -- (compile);
    \path [line] (compile) -- (view);
    \path [line] (view) -- (decide);
    \path [line] (decide) -| node [near start] {no} (edit);
    \path [line] (decide) -- node {yes} (print);
\end{tikzpicture}
\newpage

%    
    \node [block, right of=edit, node distance=3cm] (sweave) {With R\break Sweave(" *.Rnw")};

   \node [decision, below of=view, node distance=3cm] (decide) {Ready to Print?};
   \node [block, below of=decide, node distance=3cm] (print) {Print document};
%

    \path [line] (edit) -- (sweave);

Creating a Diagram of an Artificial Neural Network

One possibility; the first diagram was drawn using a matrix; the second one, using chains:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix,chains,positioning,decorations.pathreplacing,arrows}

\begin{document}

\begin{tikzpicture}[
plain/.style={
  draw=none,
  fill=none,
  },
net/.style={
  matrix of nodes,
  nodes={
    draw,
    circle,
    inner sep=10pt
    },
  nodes in empty cells,
  column sep=2cm,
  row sep=-9pt
  },
>=latex
]
\matrix[net] (mat)
{
|[plain]| \parbox{1.3cm}{\centering Input\\layer} & |[plain]| \parbox{1.3cm}{\centering Hidden\\layer} & |[plain]| \parbox{1.3cm}{\centering Output\\layer} \\

\foreach \ai [count=\mi ]in {2,4,...,10}
  \draw[<-] (mat-\ai-1) -- node[above] {Input \mi} +(-2cm,0);
\foreach \ai in {2,4,...,10}
{\foreach \aii in {3,6,9}
  \draw[->] (mat-\ai-1) -- (mat-\aii-2);
}
\foreach \ai in {3,6,9}
  \draw[->] (mat-\ai-2) -- (mat-6-3);
\draw[->] (mat-6-3) -- node[above] {Ouput} +(2cm,0);
\end{tikzpicture}

\begin{tikzpicture}[

\node[on chain=2] 
  (x2) {$x_2$};
\node[on chain=2,join=by o-latex] 
  {$w_2$};
\node[on chain=2,init] (sigma)

  (x3) {$x_3$};
\node[on chain=3,label=below:Weights,join=by o-latex] 
  (w3) {$w_3$};
\end{scope}
\node[label=above:\parbox{2cm}{\centering Bias \\ $b$}] at (sigma|-w1) (b) {};

\draw[-latex] (w1) -- (sigma);
\draw[-latex] (w3) -- (sigma);
\draw[o-latex] (b) -- (sigma);

\draw[decorate,decoration={brace,mirror}] (x1.north west) -- node[left=10pt] {Inputs} (x3.south west);
\end{tikzpicture}

[Tex/LaTex] I need pointers on how to draw the neural-network diagram

One option using TikZ; the only point that perhaps deserves some comment is the curved arrow, produced using an arc path and a decoration:

\documentclass{article}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{positioning,decorations.markings,calc}

\begin{document}

\begin{tikzpicture}[
node distance=2cm and 1cm,
mynode/.style={
  draw,
  text width=6cm,
  align=center,
  text height=3ex,
  text depth=1.5ex,
}
]
\node[mynode] (out) {Output};
\node[mynode,text width=4cm,below=of out] (sh) {State/Hidden};
\node[mynode,below=of sh] (in) {Input};

\draw[-latex] (in) -- node[fill=white] {Weights $V$}(sh);
\draw[-latex] (sh) -- node[fill=white] {Weights $W$}(out);

\begin{scope}[radius=1.2cm]
\draw[
decoration={
  markings,
  mark=at position 0.999 with {\arrow{latex}}
  },
postaction=decorate
]
(sh.16) arc[start angle=160,end angle=-150] (sh.-17);

\node[xshift=1.3cm,anchor=west,text width=2.8cm,align=center] 
at (sh.east) {Weights $U$\\(dealyed)};
\end{scope}

\node[anchor=west,text width=4cm] at ([xshift=4cm] $ (in.north)!0.5!(sh.south)$ ) {%
        $\displaystyle
        \begin{aligned}
            &y_j(t)=f(\mathrm{net}_j)\\
            &\mathrm{net}_j(t)=\sum_i v_{ji} x_i(t)+\sum_h u_{jh}y_h(t-1)+\theta_j
        \end{aligned}$
};

\node[anchor=west,text width=4cm] at ([xshift=4cm] $ (sh.north)!0.5!(out.south)$ ) {%
        $\displaystyle
        \begin{aligned}
            &y_k(t)=g(\mathrm{net}_k)\\
            &\mathrm{net}_k(t)=\sum_j w_{kj} y_j(t)+\theta_k
        \end{aligned}$
};
\end{tikzpicture}

\end{document}
