WebThe 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= (0, 1) WebApr 9, 2024 · 1. 1.
