Table 5.
Contributions of the classes predicted by our model, starting with the whole inference dataset and then moving to its cross-matches with external quasar catalogs: one spectroscopic (2QZ), providing ground truth, and 3 photometric, which are probabilistic. In those cross-matches, the highest quasar contribution is expected.
