adjust output from normalization?
Yes, just rearrange the formula for finding the normalised value. Where $x_i$ is the original attribute, and $z_i$ is the normalised value:

$$ 
\begin{align}
  z_i &amp;= \frac{x_i - min(x)}{max(x) - min(x)} \\
  x_i &amp;= z_i(max(x) - min(x)) + min(x) 
\end{align}
$$
