WebbA range of preprocessing algorithms in scikit-learn allow us to transform the input data before training a model. In our case, we will standardize the data and then train a new logistic regression model on that new version of the dataset. Let’s start by printing some statistics about the training data. data_train.describe() age. Webb引言. 我们在上一篇SKLearn入门与简单应用案例里给大家讲到了SKLearn工具的基本板块与使用方法，在本篇内容中，我们展开讲解SKLearn的进阶与核心内容。 SKLearn中有六大任务模块，如下图所示：分别是分类、回归、聚类、降维、模型选择和预处理。 teams it admin readiness

The samples matrix (or design matrix) X.The size of X is typically (n_samples, n_features), which means that samples are represented as rows and features are represented as columns..
