What is a normalized range of values?
It depends on a normalization technique but yes. If we use min max it will always be between [0,1]. What you can do is split that variable into segments and the normalized your data. However you use minx-max normalization, the minimum value of that feature gets transformed into a 0, and the maximum value gets a 1. Maybe a
mean normalization could give you a different result in that case.
I'm studying k-anonymization and the mondrian algorithm proposed by LeFevre. In it, LeFevre says that at one point in his algorithm, we have to choose a feature in the Dataframe depending on which feature has the largest range of normalized values.
For example, if I have the feature Age in my dataset with the values:
[13, 15, 24, 30], I understand that the range is 13-30, but as soon as you make it normalized wouldn't it always be [0-1]?
I know that the question seems strange, but I couldn't find anything on the internet nor on the paper itself that documented more what he meant.
