Issam, currently, GaussianNB does not support sample weights thus it cannot be used w/ Adaboost. In Weka, if a classifier does not support sample weights they fall back to data set re-sampling. We could implement this strategy as well but it would not be very efficient due to the data structures that we use internally (i.e. numpy arrays).
