True versus estimated redshift values for Darth Fader (top row), dictionary learning (middle row), and denoising autoencoders (bottom row) in the S/N = 20, 5, and 2 cases (left, middle, and right columns, respectively). Galaxies are divided by type: ellipticals and lenticulars (EllS0, blue circles), regular spirals (SaSc, orange squares), broken/irregular spirals (SdSm, green triangles), and starbursts (SB, red crosses).
