The success of this experiment at low redshift opens promising perspectives for upcoming surveys. We argue that for most galaxies the precision is limited by the S/N of SDSS images rather than by the method. We developed a deep convolutional neural network (CNN), used as a classifier, to estimate photometric redshifts and associated probability distribution functions (PDF) for galaxies in the Main Galaxy Sample of the Sloan Digital Sky Survey at z 100, as in the deep stacked region of Stripe 82.
