dmHomework1

数据挖掘的第一次互评作业。

本次作业使用的数据集为Wine Reviews与Chicago Building Violations。

【由于频数统计、五数概括文件过多,因此没有在报告中详细介绍,详情请见文件夹内】

使用说明:

数据集:

数据集应该放在根目录的data文件夹下。

代码:

对数据集Wine Reviews与Chicago Building Violations进行处理的python文件分别为wine_process.py和building_process.py,运行时放在根目录下。

结果:

nominal文件夹下存放的是标称属性的频数统计结果,以txt文件保存;

numberical文件夹下存放的是数值属性的五数概括和缺失值(missingValues.txt),以txt文件保存,以及数值属性的直方图以及盒图;

delete文件夹下存放的是将缺失部分剔除后的可视化结果;

mod文件夹下存放的是用最高频率值来填补缺失值后的可视化结果;

related文件夹下存放的是通过属性的相关关系来填补缺失值后的可视化结果;

similarity文件夹下存放的是通过数据对象之间的相似性来填补缺失值后的可视化结果。
