Percent values for the confusion matrices obtained from the classification of different subsamples of AGN in the LS for each test: only sAGN1 (upper left); only sAGN2 (upper center); sAGN1 plus sAGN2 (upper right); sAGN1, sAGN2, and Donley non-sAGN (lower left); MIR AGN (lower center); sAGN1 plus sAGN2, with r ≤ 21 mag (lower right). True Label is the one we used to include the sources in the LS, as detailed in Sect. 2.5. Predicted Label is the outcome of the classification. Each percent error is the standard deviation from the average value obtained from a set of ten simulations per classifier, where each classifier builds each time 500 trees in order to determine the final classification for each source.
