如何在weka中添加分类器?

标签: weka classification

我想向Weka添加自定义分类器。此分类器位于jar文件中。我已将它放入Weka文件夹并运行此命令java -classpath "D:/weka/ancl.jar;D:/weka_bin/weka.jar" weka.gui.GUIChooser Weka正常运行但我在分类器列表中找不到我的分类器。

我也试过这个分类器到GenericObjectEditor.props文件,但是当我用上面的命令运行weka时,当我点击Explorer按钮时我得到了这个异常

$ java -classpath "D:/weka/ancl.jar;D:/weka_bin/weka.jar"  weka.gui.GUIChooser
