    Default Not able to get results with Random Forest in WEKA

    Hello Sir/Mam,


    I am building classification model based on random forest but every time i am getting the following output.

    -------------------------------------------------------------------------------

    Classifier Model
    RandomForest

    Bagging with 100 iterations and base learner

    weka.classifiers.trees.RandomTree -K 0 -M 1.0 -V 0.001 -S 1 -do-not-check-capabilities

    Time taken to build model: 101.6 seconds
    -----------------------------------------------------------------------------

    I used same dataset with SMO, J48 etc but i was able to get results for them.

    Kindly Help

    Default

    Turn on the "printClassifiers" option - this will output the textual representation for each of the trees in the forest. They are not output by default because OOM errors can occur when forming a string containing very large forests.

    Cheers,
    Mark.
