    Default Parameters for J48 Tree


    I'm using the J48 Tree for classification. It support lots of parameters.

    Which parameter ranges should I search for? I'm especially unsure about the following settings:

    runing confidence
    minimum number of instances

    Second, how can I implement Bagging with a J48 classifier in WEKA?

    EDIT: I have just seen that some methods like buildClassifier() throws an Exception of type Exception. Why in gods name is this done? Throwing these unspecific exceptions is not so good programming style.
