Accuracy of ResNet regression for inferring Ω_m, σ₈, A_SN1, A_AGN1, A_SN2 and A_AGN2 from simulation-based XODs. The colour and contours show the shape of the density of points (arbitrary colour scale, all densities are normalised). The dashed line shows the 1:1 line (no error). We observe that the two cosmological parameters are well recovered. The SN feedback parameters are also rather well estimated, although with a stronger scatter. However, the ResNet struggles to retrieve the AGN feedback parameters, meaning that these parameters do not significantly influence our XOD statistics.
