Web3 feb. 2024 · MinMax Scaler shrinks the data within the given range, usually of 0 to 1. It transforms data by scaling features to a given range. It scales the values to a specific value range without changing the shape of the original distribution. The MinMax scaling is done using: x_std = (x – x.min (axis=0)) / (x.max (axis=0) – x.min (axis=0)) Web10 jun. 2024 · StandardScaler and MinMaxScaler are not robust to outliers. Consider we have a feature whose values are in between 100 and 500 with an exceptional value of 15000. If we scale this feature with MinMaxScaler(feature_range=(0,1)), 15000 is scaled as 1 and all the other values become very close to the lower bound which is zero.Thus, … WebMinMaxScaler (copy=True, feature_range= (0, 1)) In [5]: training_set_scaled = sc.fit_transform(training_set) # 求得训练集的最大值,最小值这些训练集固有的属性,并在训练集上进行归一化 test_set = sc.transform(test_set) # 利用训练集的属性对测试集进行归一化 print(training_set_scaled[:5,]) print(test_set[:5,]) coordinate converter geocaching
