Hello. I am using ensemble classifiers in the Matlab Classification Learner. The problem is that I am getting different accuracies when training the same classifier (Bagged Trees) on the same data.

Most of the classifiers include random initialization. To repeat the same accuracy with the same classifier on the same data, set the random number seed each time, using rng()

In such a case you have to assume that there is a lot of over-fitting. Reduce the size of your training set and increase the size of your test set.
