一般使用weka进行数据挖掘的时候会碰到两个问题,一是内存不够,二是libsvm使用不了,这时就需要重新配置RunWeka.ini文件,解决上述问题。查看RunWeka.ini原文如下:

 1 # Contains the commands for running Weka either with a command prompt
 2 # ("cmd_console") or without the command prompt ("cmd_default").
 3 # One can also define custom commands, which can be used with the Weka
 4 # launcher "RunWeka.class". E.g., to run the launcher with a setup called
 5 # "custom1", you only need to specify a key "cmd_custom1" which contains the
 6 # command specification.
 7 #
 8 # Notes: 
 9 # - This file is not a DOS ini file, but a Java properties file.
10 # - The settings listed here are key-value pairs, separated by a "=". Every
11 #   key can only be listed ONCE.
12 #

16 # setups (prefixed with "cmd_")
17 cmd_default=javaw -Dfile.encoding=#fileEncoding# -Xmx#maxheap# #javaOpts# -classpath "#wekajar#;#cp#" #mainclass#
18 cmd_console=cmd.exe /K start cmd.exe /K "java -Dfile.encoding=#fileEncoding# -Xmx#maxheap# #javaOpts# -classpath \"#wekajar#;#cp#\" #mainclass#"
19 cmd_explorer=java -Dfile.encoding=#fileEncoding# -Xmx#maxheap# #javaOpts# -classpath "#wekajar#;#cp#" weka.gui.explorer.Explorer
20 cmd_knowledgeFlow=java -Dfile.encoding=#fileEncoding# -Xmx#maxheap# #javaOpts# -classpath "#wekajar#;#cp#" weka.gui.beans.KnowledgeFlow
21 
22 # placeholders ("#bla#" in command gets replaced with content of key "bla")
23 # Note: "#wekajar#" gets replaced by the launcher class, since that jar gets
24 #       provided as parameter
25 maxheap=1024M
26 # The MDI GUI
27 #mainclass=weka.gui.Main
28 # The GUIChooser
29 mainclass=weka.gui.GUIChooser
30 # The file encoding; use "utf-8" instead of "Cp1252" to display UTF-8 characters in the 
31 # GUI, e.g., the Explorer
32 fileEncoding=Cp1252
33 # The JAVA_OPTS environment variable (if set). Can be used as an alternative way to set
34 # the heap size (or any other JVM option)
35 javaOpts=%JAVA_OPTS%
36 # The classpath placeholder. Add any environment variables or jars to it that
37 # you need for your Weka environment.
38 # Example with an enviroment variable (e.g., THIRD_PARTY_LIBS):
39 #   cp=%CLASSPATH%;%THIRD_PARTY_LIBS%
40 # Example with an extra jar (located at D:\libraries\libsvm.jar):
41 #   cp=%CLASSPATH%;D:\\\\libraries\\\\libsvm.jar
42 # Or in order to avoid quadrupled backslashes, you can also use slashes "/":
43 #   cp=%CLASSPATH%;D:/libraries/libsvm.jar
44 cp=%CLASSPATH%

其中maxheap选项为配置weka最大使用内存,默认为1024M;

  cp选项为引入包所在路径,从注释中的说明可以看到libsvm包的添加方法;

  其他如:mainclass,fileEncoding,javaOpts分别为图形用户界面,文件编码,Java虚拟机选项。
