Redshifts inferred from the v0, v1, v2, and v3 models for a sample of [OII] emission line galaxy candidates at z ≈ 1.47 in the DEEP2 field. Their ugrizy SED-fitting redshift distribution is shown in green. The 526 C2020 redshifts available for such galaxies in the COSMOS field are shown as hatched histograms and the spectroscopically confirmed cases in all the fields combined as gray-filled histograms. The corresponding metrics, in the top right corner of each panel for the CNN, and in green and gray for the ugrizy and C2020 redshifts respectively, assume a true redshift z_{E L}=1.4657 (red vertical line, see text for details).
