Low Variance Filter: Normalize?

Reading the description for Low Variance filter I see this:


Note, the input table should not be normalized.

I always assumed all columns must be normalized to the same range or else the variance threshold will have a different effect on each column? Or does the node do internal normalization? Or is it a documentation error?

Hi @beginner,

What is meant with “the input table should not be normalized” is that it should not be Gaussian normalized since this is changing the variance. If you want to have it normalized in between 0 and 1 or not, is up to you. The node itself does not perform any normalization, you need the Normalization node for this task.
