"How to Visualize Weka Random Forest Tree Model?"

Dear everyone,

When I use the RapidMiner Random Forest to train a tree classifier, I can link the "mod" to "res" to visualize how the trees are constructed in the result perspective. I would like to know how I can visualize the tree model when I use the Weka Random Forest. It seems that linking "mod" to "res" doesn't work.

Thanks.
Gary

    Hi,
    you simply can't. Weka doesn't support a renderer for this as long as I know.

    If I set "I=100, K=1, S=1, depth=0" in Weka Random Forest and train a classifier, is there any way that I can  set the RapidMiner Random Forest so that it would have the same setting as the Weka one and generate a similar classifier so that I can visualize how each tree looks like?

    Regards.

    Hi,
    no you can't. Both algorithms share the same idea but are implemented completely different.
