Central galaxy spectroscopic redshift versus its photometric redshift measured with and without NezNet. The left panel shows the distribution of photometric vs. spectroscopic estimates in the original data. In the middle panel, we show the same distribution after removing the galaxies with low score probability from the catalogue (fr stands for the fraction of retained data). Finally, the right panel shows redshift estimates by assigning the spectroscopic redshift of the neighbour with the highest detection probability to the target galaxy. The model was trained with n_NN = 30 and Δz = 0.08.
