visualize a tree and splitting point in TreeBagger

6 views (last 30 days)
Hi, Suppose I fit a TreeBagger with 2 column predictor variables X:
B = TreeBagger(1,X,y, 'Method','classification','NVarToSample',1,'oobpred','on')
I want to visualize any tree that I choose, and the splitting values. How can I do that? Thanks!

doc TreeBagger and take a look at the Trees property. For example, to see the first tree
view(B.Trees{1})

What I said about the view method is not in the TreeBagger doc. Typing
B.Trees{1}
returns an object for a single tree. If you use R2013a or later, the class is included in the display of this object. (If you use an earlier release, you can infer the class of this object from the variable editor, for instance.) You can then go to the doc for that class.

Hi, How can I increase the number of iterations for fitting a decision tree or random forest? Also, how can I change the opimizer from Bayesian to other such as grid search
