Identifying catastrophic outlier photometric redshift estimates in the COSMOS field with machine learning methods
Mitchell T. Dennis, Esther M. Hu, Lennox L. Cowie
We present the result of two binary classifier ensembled neural networks to identify catastrophic outliers for photo-z estimates within the COSMOS field utilizing only 8 and 5 phot…
