如何将分类器添加到weka？

【问题标题】：How to add classifier to weka?如何将分类器添加到weka？
【发布时间】：2012-08-12 05:43:54
【问题描述】：

我想将自定义分类器添加到 Weka。这个分类器在 jar 文件中。我已将其放入 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 运行正常，但我在分类器列表中找不到我的分类器。

我也尝试将此分类器添加到 GenericObjectEditor.props 文件，但是当我使用上面的命令运行 weka 时，当我点击资源管理器按钮时出现此异常

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

谁能告诉我 Weka 中的自动类发现是如何工作的？或者为什么它不实际:( 任何帮助appricieted

【问题讨论】：

    标签： weka classification


    【解决方案1】：

    在创建 jar 时将 Java_cup、Meta_Inf 和 weka 文件夹合并在一起，然后上述错误将消失。

    【讨论】：

    • 你能补充一些细节吗？你如何一起创造它们？
    【解决方案2】：

    我按照这些说明进行操作，一切都很好：

    https://waikato.github.io/weka-wiki/writing_classifier/

    快速浏览一下结尾：

    这是一个调用 weka.classifiers.trees.Id3 和生成的类 weka.classifiers.WekaWrapper 的示例（它将实际生成的代码包装在一个伪分类器中）：

    java weka.classifiers.CheckSource \
    -W "weka.classifiers.trees.Id3" \
    -S weka.classifiers.WekaWrapper \
    -t data.arff \
    -c last
