Compile and Test C5.0

1. download source code of C5.0 from http://www.rulequest.com/GPL/C50.tgz

2. 解壓後進入目錄,開始編譯

make

得到以下錯誤:

make: /bin/csh: Command not found

3. 安裝必要組建:

sudo apt-get install tcsh


4. 編譯後生成可執行文件: c5.0


5. 測試,使用數據集合soybean, 可以從uci上下載,我使用了其自帶的。

5.1 (a)一般測試:

./c5.0 -f Samples/soybean
(b) 結果
