MinMaxScaler(feature_range = (0, 1)) 将在[0,1] 范围内按比例转换列中的每个值。将其用作转换特征的第一个缩放器选择,因为它将保留数据集的形状(无失真)。 StandardScaler() 将列中的每个值转换为均值 0 和标准差 1 左右的范围,即,每个值将通过减去均值并除以标准差来归一化。如果您知道数据分布是正常...

Standard Scaler Train,Platform For AI:In data preprocessing, user can standardize data to reduce the effect caused by the data volume and range in each column. After standardization, data in different columns falls within the same data ra...
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)...
