I have a question in regard to viewing the Tree from the fitensemble function. I am using 'RUSBoost' as the method. I can see that there are 1000 trees in the cell called Trained since I set nlearn to be a 1000. So these 1000 trees are the weak learners if I am not mistaken. But then where is the strong learner that was gotten using these weak learners? In other words, where is the tree that is actually used for prediction? How can I see that tree?
Thank you for your help.

The strong learner is the ensemble. An ensemble is a collection of trees. It predicts by averaging predictions from individual trees. This average is weighted. You can get the weights from the TrainedWeights property of the ensemble object.
