How to draw horizontal diagram flow

How can I draw using TikZ the following horizontal diagram without the border and only the figure? • Do you really need the 3D/shadowing effect? It complicates matters without really adding anything. – John Kormylo Jan 31 at 19:40

Welcome to TeX.SE! The purpose of this site is to help you if you have problems with a code, not to convert screen shots to a code. I hope that this code gives you enough motivation to try yourself.

\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}

\begin{tikzpicture}
\begin{scope}[start chain = going below,
every node/.append style={on chain,fill opacity=0.8,draw,
join},every join/.style={thick,-latex},
]
\node[fill=white,cs] (N1) {\begin{tabular}{p{1cm}cp{1cm}}
Input & $y$ &\\
& \tiny NX2 &
\end{tabular}};
\node[fill=orange,cs] (N2) {\begin{tabular}{c}
Conv1D Layer\\
\tiny NX2
\end{tabular}};
\node[fill=orange,cs] (N3) {\begin{tabular}{c}
Conv1D Layer\\
\tiny NX2
\end{tabular}};
\node[circle,minimum size=8mm,thick,font=\Huge\bfseries] (C) {+};
\node[fill=white,cs] (N4) {\begin{tabular}{p{1cm}cp{1cm}}
Output & $q_\Phi(x,y)$ &\\
& \tiny NX2 &
\end{tabular}};
\end{scope}
\path (N1) -- (N2) coordinate[pos=0.5] (aux);
\draw[thick,-latex] (aux) to[out=0,in=30,looseness=2.7] (C);
\path (N2) -- (N3) node[pos=0.5,right,font=\bfseries\itshape]{SoftSign};
\path (C) -- (N4) node[pos=0.5,right,font=\bfseries\itshape]{Sigmoid};
\end{tikzpicture}
\end{document}
