adjust output from normalization?

Question

I've trained a neural network network that given a minmax normalized input, provides a minmax normalized output.

this might be late, but is it possible from a minmax normalized output to create the actual output, given you know the actual min and max value?

so an unormalized output?

Answer 1

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

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