Download the zip files and build models.
zip压缩文件可用于模型开发。

Extra notes | 备注:

1. The first column in each dataset is the target variable, prefixed with "target_", e.g., "target_survived" or "target_Class".
   每个数据集中第1列为目标变量，以 "target_" 开头，例如，"target_survived" 或者 "target_Class"。


2. The original class variable in some datasets may have more than 2 values, we have binarized them for binary classification modeling. Read source code for the treatments.
   某些数据集的原始分类变量可能含有2个以上的取值，我们进行了二值化处理使数据集能够进行二分类建模。源代码中有详细处理逻辑。


3. Due to the lack of domain knowledge, data treatments may not be best-practices. Please create a new zipped data file by modifying the source code.
   由于缺少相关领域知识，某些数据处理步骤可能并非最佳实践。请修改源代码后重新生成压缩的数据文件。
