UMAP embeddings from a deep convolutional layer, colored by redshift. The leftmost panels displays a COSMOS UDF validation sample from the baseline training, colored by redshift labels. The middle and right panels show the embeddings from the same layer for DEEP2 unlabeled galaxies, colored by redshift predictions, before and after DA (v0 vs. v2), respectively. The top and bottom rows make use of galaxy samples with i<22 and i>23, respectively.
