TL;DR: In this paper, a study of the photometric redshift performance of the Dark Energy Survey (DES), using the early data from a Science Verification (SV) period of observations in late 2012 and early 2013 that provided science-quality images for almost 200 sq.deg.

ArborZ: Photometric Redshifts Using Boosted Decision Trees
D. W. Gerdes,A. Sypniewski,Timothy A. McKay,Jiangang Hao,Jiangang Hao,Matthew Weis,Risa H. Wechsler,Michael T. Busha +7 more
TL;DR: In this article, a boosted decision tree (BDF) is used to estimate the photometric redshift of each galaxy, not only a single best estimate and error, but also a photo-z quality figure of merit for each galaxy that can be used to reject outliers.
