CNN performance for various convergence regions selections, when excluding shape noise. Top panel is σ_S8, the constraining power on S₈, bottom panel is H, the information entropy. Low/mid/high κ denotes the low/mid/high convergence regions. The second row presents the performance of a network taking as input the high convergence regions in one channel and the Fourier transform amplitude in another, to mimic a summary statistics analysis method capable of extracting non-Gaussian information: the combination of the PS and peak counts/Minkowski functionals.
