WebbMinMaxScaler ¶. MinMaxScaler rescales the data set such that all feature values are in the range [0, 1] as shown in the right panel below. However, this scaling compresses all inliers into the narrow range [0, 0.005] for the transformed average house occupancy. Both StandardScaler and MinMaxScaler are very sensitive to the presence of outliers.
