However, when used as a \"black box\", neural networks are not robust to baryonic uncertainty. We propose a robust architecture for constraining primordial non-Gaussianity $f_{NL}$, by training a neural network to locally estimate $\\sigma_8$, and correlating these local estimates with the large-scale density field. We apply our method to N-body simulations, and show that $\\si","authors_text":"Kendrick M.
