CosmicNet II: Emulating extended cosmologies with efficient and accurate neural networks

lesgourg/class_public 12 Jul 2022

We have eliminated the perturbation module as a bottleneck of the EBS, with a speedup that is even more remarkable in extended cosmologies, where the usual approach would have been more expensive while the network's performance remains the same.
