Results of our probabilistic classification of COSMOS-Web galaxies with XGB with imputation, as in the NUVrJ (left column), NUVrK (middle column), and SFR–M (right column) planes. Each hexagon is color-coded by the mean quiescent probability (scale bar on the right), with rows corresponding to different redshift bins. As expected from our training, the method consistently reproduces classical cuts (white lines), while also providing additional insight near the classification boundaries. Classification is ambiguous for some low-mass galaxies at low redshift (light blue region in the top panels).
