Random forest: output decision tree

Postby droidzoid » Thu May 23, 2013 19:58

Hi,

I found the possibility to visualize single decision trees from a random forest in the help.

But it seems there's no tree output in the random forest anymore. Is there another possibility to visualize a random forests' decision tree?

thx

The output was removed after the base tree learner used by the Random Forest was replaced with an faster and simpler implementation, which however does not expose the tree model to python.

The documentation for the widget needs to be fixed.

A copy of the widget (named "Random Forest (Old)") using the old base learner and the "Chosen tree" output was put in the Prototypes widget category.
If you downloaded orange before the last week, you will need to enable the Prototypes.
