Per feature relative scaling of the data to achieve zero mean and unit variance. Generally this is calculated using np.sqrt (var_). If a variance is zero, we can’t achieve unit variance, and the data is left as-is, giving a scaling factor of 1. scale_ is equal to None when with_std=False.

WebNormalization in machine learning is the process of translating data into the range [0, 1] (or any other range) or simply transforming data onto the unit sphere.
