Notes.XGBoost Test set RMSE, bias, OLF, and NMAD for different redshift intervals, SED types, number of missing bands and i-band magnitudes. The redshift range 2 ≤ z < 8 comprises all the galaxies in the test set. Objects with i > 29.3 are not detected in the i-band.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
