centos6.3 安装weka

下载：http://www.cs.waikato.ac.nz/ml/weka/downloading.html

Click here to download a zip archive containing Weka
(weka-3-6-9.zip; 22.9 MB)

First unzip the zip file. This will create a new directory called weka-3-6-9. To run Weka, change into that directory and type

java -Xmx1000M -jar weka.jar

Note that Java needs to be installed on your system for this to work. Also note, that using-jar will override your current CLASSPATH variable and only use theweka.jar.
