+The second machine learning experiment
+
+About this repository:
+
+1. Because the system extract the file according to the file name, please do not rename the file *ClassificationExperiment.ipynb* and *RegressionExperiment.ipynb*.
+2. .ipynb is the suffix of the jupyter botebook file, which can be viewed and edited in jupyter.
+3. There are two versions of the report template(Chinese version and English version), report-en.docx and report-en.docx. Because the system extract the file according to the file name,, if you complete the Chinese report, rename report-zh.docx to report.docx; if you complete the English report, rename report-en.docx to report.docx.
+4. The reference code will also be published in this repository after all the students have submitted.

+
+关于本仓库：
+
+1. 因为最终系统是按照文件名称抓取代码文件，所以请勿更改ClassificationExperiment.ipynb和RegressionExperiment.ipynb的文件名。
+2. .ipynb是jupyter botebook文件的后缀名，在jupyter中可以查看并编辑。
+3. 报告的模板有两个版本，中文版和英文版，分别是report-zh.docx和report-en.docx。因为最终系统是按照文件名称抓取报告的，如果填写中文报告，请把report-zh.docx重命名为report.docx；如果填写英文报告，请把report-en.docx重命名为report.docx。
+4. 参考代码也会在所有同学都提交完毕后公布在本仓库中。
