Graphics, Figures & Tables ⇒ Back Propagation NN Tikz Diagram

[jakob1992]

I am trying to figure out how to draw this diagram in either tikz or svg:



I tried few codes but feeling overwhelmed by the complexity of this figure since I am new to tikz drawings. Any help will be appreciated. Thank you!

Hi Jacob,

welcome to the forum!

Perhaps show what you already tried, so we can help extending it or improving it, or possibly come up with similar or different suggestions.

Thank you, Stefan. One of the fellow users provided this code and gave me a head-start. However, since this is my first time working with tikz and on such a complicated figure, I am completely lost on how to proceed and finish drawing this. Here's the code:

Code: Select all

\documentclass[tikz]{standalone}
\usetikzlibrary{decorations.markings}

\begin{document}
\begin{tikzpicture}[
  dot/.style={
    circle, draw, inner sep=1.5pt
  },
  arrow/.style={
    decoration={markings,
    mark=at position 0.5 with {\arrow{latex}}},
    postaction={decorate}
  }
]

\node[dot, label={90:$\upsilon_1^{(1)}$}] (u11) at (0,0) {};

\node[dot, label={300:$\varphi^\prime(\cdot)$}] (p1) at (0,-2) {};

\node[dot] (x1) at (2,-2) {};

\node[dot, label={270:$\delta_1^{(1)}$}] (d11) at (0,-5) {};

\draw[arrow] (u11) -- node[pos=.5, label={180:$\varphi^\prime(\cdot)$}] {} (p1);
\draw (p1) -- (x1);
\draw[arrow] (p1) -- (d11);

\end{tikzpicture}
\end{document}

Please let us know about your crossposts.

Yes, that's what I said. I didn't get much help on that forum, so I turned to this one to see if someone can Kindly help instead of pointing out crossposts.

Hi Jacob,

yes, you mentioned it. Cross-posts are ok, it's just important to add a link to the other site. In case it would have been solved at the other site, I may sit here and build that complex diagram because I don't know it's already done. With a link, I could know that. That's the simple reason why Bartman added the link.

In the meantime somebody wrote the whole diagram for you in the other forum. Without the link to the cross post, a reader would not have known it and perhaps tried some time himself/herself.

Anyway, good that you got a solution, a next time just mention a crosspost with a link to it, or just post only here.

Stefan
