Left: Comparison of the NDE’s cosmological prediction with a Fisher prediction on the same target XOD corresponding to a 1000 deg² survey area. Right: Comparison of the NDE’s cosmological results for four different survey areas. The NDE’s was trained on our D1 dataset, with dn/dz selection and free γ parameters. The y-axis in the 1D posterior probability distribution plots indicates the probability density at each parameter value shown on the x-axis. Each 1D probability density function is normalized in a way that the total area under its curve equals 1.
