Witryna11 lip 2014 · An alternative approach to Z-score normalization (or standardization) is the so-called Min-Max scaling (often also simply called “normalization” - a common cause for ambiguities). In this approach, the data is scaled to a fixed range - usually 0 to 1. WitrynaThe transformation is given by: X_std = (X - X.min(axis=0)) / (X.max(axis=0) - X.min(axis=0)) X_scaled = X_std * (max - min) + min where min, max = feature_range. This transformation is often used as an alternative to zero mean, unit variance scaling. Read more in the User Guide. Parameters: feature_rangetuple (min, max), default= …
