%% View Tree from Boosted Ensemble %% % Load Fisher's iris data set. load fisheriris %% % Boost an ensemble of 100 classification trees using all measurements. Mdl = fitensemble(meas,species,'AdaBoostM2',100,'Tree'); %% % |Mdl| is a <docid:stats_ug.bstzl0v-1 |ClassificationEnsemble|> model object. % |Mdl.Trained| stores the ensemble of 100 trained classification trees in a % 100-by-1 cell array. That is, each cell in |Mdl.Trained| contains a % |CompactClassificationTree| model object. %% % View a graph of the 10th classification tree in the ensemble. Tree10 = Mdl.Trained{10}; view(Tree10,'Mode','graph'); %% % By default, |fitensemble| grows shallow trees for boosted ensembles of % trees.
