New config at https://github.com/jiweiqi/CellBox.jl/blob/main/Test_Beeline/Curated/mCAD/config.yaml The neural network part is realized by reloading the ode function.

List of possible architectures (mu: perturbation, \alpha, \epsilon are scaling factors)

• du = NN(u, mu)
• du = NN(u, mu) - \epsilon u
• du = NN(u) - \alpha mu - \epsilon u
• du = \alpha .* tanh(NN(u) - mu) - \epsilon u
