Representation of the model p(I_main|M_500c, z) predicting a cluster to be detected and selected with an extent likelihood above three. The explanatory variables (features) are labels attached to simulated clusters in the twin simulation, standing for galaxy cluster M_500c mass and cosmological redshift. The bottom-left panel represents contours of equal detection probability, labelled in steps of 0.1. Both one-dimensional curves (top-left and bottom-right panels) are slices through the function displayed in the bottom-left corner, at fixed z = 0.3 and M_500c = 3 × 10¹⁴ M_⊙ (indicated with dotted lines).
