weka构建Attribute
构建Attribute时,将分类属性加载入hashtable,构建模型时,将用到的分类属性与hashtable中的记录进行对比,失败报错
Attribute gender = new Attribute( "Weight", genderCategory);
public DataObject delegator(String className, String methodName,
DataObject para) throws Exception{
//查找客户化表,获取客户化的类
String customClassName = getCustomClass(className);
//查找客户化表,获取客户化的方法
String customMethodName = getCustomMethod(methodName);
Class<?> c = Class.forName(customClassName);
//获取客户化的类的实例
Object o = c.newInstance();
Method m = o.getMethod(customMethodName, DataObject.class);
DataObject result;
try{
//执行客户化的方法
result = m.invoke(o, para);
} catch(InvocationTargetException e)[
throw e.getCause();
}
return result;
}
