Behavior of data scaling algorithms with/without outliers. Top panels a–c: when there is no outlier in the data, the behavior of the Min-max algorithm, Z-score algorithm and the GL algorithm is very similar. Bottom panel d–f: when there is an outlier in the data, the behaviors of the Min-max algorithm and Z-score algorithm are significantly affected, but the impact of the outlier on the GL algorithm is neglectable
