                  [0],
                  [100.1],
                  [900.9]])

    # Rescale Feature Using Min-Max
    # Create scaler
    minmax_scale = preprocessing.MinMaxScaler(feature_range=(0, 1))

    # Scale feature
    x_scale = minmax_scale.fit_transform(x)

    # Show feature
    print(); print(x)
    print(); print(x_scale)
