: A Fast Memory-based Emulator of the Global 21 cm Signal with Unprecedented Accuracy
J. Dorigo Jones, S. M. Bahauddin, D. Rapetti +2
Neural network (NN) emulators of the global 21 cm signal need emulation error much less than the observational noise in order to be used to perform unbiased Bayesian parameter infe…
