机器学习——特征标准化、归一化、缩放、二值化

Webnp.concatenate( [-np.inf, bin_edges_[i] [1:-1], np.inf]) You can combine KBinsDiscretizer with ColumnTransformer if you only want to preprocess part of the features. KBinsDiscretizer might produce constant features (e.g., when encode = 'onehot' and certain bins do not contain any data). Web数据预处理: 将输入的数据转化成机器学习算法可以使用的数据。包含特征提取和标准化。 原因:数据集的标准化(服从均值为0方差为1的标准正态分布(高斯分布))是大多数机器学习算法的常见要求。. 如果原始数据不服从高斯分布,在预测时表现可能不好。 florida man news titles https://lovetreedesign.com
