WebbThis estimator scales and translates each feature individually such that it is in the given range on the training set, e.g. between zero and one. The 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. jedna sa o
