因此,StandardScaler 不能保证在异常值存在的情况下平衡特征尺度。 MinMaxScaler 数据集,使所有特征值都在 [0, 1] 范围内,如下面右侧面板所示。但是,对于转换后的家庭数量,此缩放比例会压缩窄范围 [0, 0.005] 内的所有异常值。 原文由 Simas Joneliunas 发布,翻译遵循 CC BY-SA 4.0 许可协议有用 回复 社区维...

I believe the issue is that fit_transform does not really store the mean and standard deviation. You need to first fit the transform using: scaler = preprocessing.StandardScaler(); scaler.fit(X) df_scaled = scaler.transform(X) # In your prediction step clf.predict(scaler.transform(query_df)...
Standard Scaler ValueError Question: I am getting a error as: ValueError: Expected 2D array, got 1D array instead: array=[ 45000. 50000. 60000. 80000. 110000. 150000. 200000. 1000000.]. When I execute the line y = sc_y.fit_transform(y)...
