Sklearn preprocessing maxabsscaler
Webb最大值绝对值标准化（MaxAbs）即根据最大值的绝对值进行标准化，假设原转换的数据为x，新数据为x'，那么x'=x/ max ， 其中max为x锁在列的最大值。 该方法的数据区间为[-1, 1]，也不破坏原数据结构的特点，因此也可以用于稀疏数据，一些稀疏矩阵。 针对离群点的RobustScaler 有些时候，数据集中存在离群点，用Z-Score进行标准化，但是结果不理 … Webb27 juni 2024 · sklearn.preprocessing.scale 函数 scale 提供了一种在单个类似数组的数据集上执行标准化操作的快捷方法： (也就是特征向量减去平均值除以标准差) 1 2 from sklearn import preprocessing import numpy as np 1 2 3 np.random.seed (1) X …

WebbFit RobustScaler. Scale features using statistics that are robust to outliers. This Scaler removes the median and scales the data according to the quantile range (defaults to IQR: Interquartile Range). The IQR is the range between the 1st quartile (25th quantile) and the 3rd quartile (75th quantile). Centering and scaling happen independently ...
