Hi Chris,
great work! Excellent package and tutorial.
I am a newbie in Julia but I appreciated your new take on the neuro-ode that I had to try your code.
While attempting to clone, precompile, an…

I accidentally stopped the tracking in the neural_ode layer and of course it can't backprop through since what comes out is just a float (@MikeInnes told me this would happen). So an MWE of trying to …

Hello everyone!
I am trying to use this Package, but I have some questions.
What I am trying to do is predict the time series of the [Lotka-Volterra](https://en.wikipedia.org/wiki/Lotka–Volterr…

The logpdf function in the build_loss_objective is not set up properly.
What should take place? For a simple demo model like Lotka-Volterra or Lorenz and ONE DATASET, fit_mle should fit a MvNormal…

Please add an example showing how a diff. eq. can be assembled from ikaros modules.
For example:
* damped oscillation
* Lotka-Volterra equations for predator prey dynamics
This would be a useful…
