Given a network with the size vector $\bm{s}=(\rint, \rint, \rint, \rint)^\top$, determine $n$, $K$, $L$ and write the dimensionality of:
%
\begin{align*}
  \bm{x}            \\
  \bm{\hat x}       \\
  \bm{a}^{(1)}      \\
  \bm{\hat a}^{(1)} \\
  \bm{\Theta}^{(1)} \\
  \bm{z}^{(2)}      \\
  \bm{a}^{(2)}      \\
  \bm{\hat a}^{(2)} \\
  \bm{\Theta}^{(2)} \\
  \bm{z}^{(3)}      \\
  \bm{a}^{(3)}      \\
  \bm{\hat a}^{(3)} \\
  \bm{\Theta}^{(3)} \\
  \bm{z}^{(4)}      \\
  \bm{a}^{(4)}      \\
  \bm{\hat a}^{(4)} \\
  h_{\bm{\Theta}}(\bm{x}) \\
  \bm{y}
