这是我从weka主页上下载的一个c4.5算法的改进算法,里面附有readme文件,只有算法的主体,大约600行代码-weka from the home page to download an algorithm Bank improved algorithm inside with the readme file, only the main algorithm, about 600 lines of code

一个相对很完善的数据挖掘系统（少部分功能欠缺），不仅包括了按类Association（内含Apriori，C4.5，GrowTree）,Classification(ID3),Cluster划分常用的算法及个人优化后的算法。同时包含了多种数据源（MS Access，Excel，SQL Server，TEXT）的界面直接连接方式。界面方面更像一个专业的系统，采用了类VC浮动多框架界面，也可以作为界面编程的参考。这个工程的分数和其他小工具的分数一样，感觉亏大了:)-A relatively well
