We have trained perceptron multilayer neural networks for flat and non-flat cosmological models in the 6(7) dimensional parameter space: omega_bh^2, omega_ch^2, (omega_k), theta, tau, n_s and ln A_s and plan to release networks for other models in due course. ... CosmoNets neural network maps are very simple and typically contain a small number of thousands of parameters (weights). ...
