I watched the JuliaCon 2018 | [PuMaS.jl: Pharmaceutical Modeling and Simulation Engine](https://www.youtube.com/watch?v=KQ4Vtsd9XNw) given by @ChrisRackauckas and saw the part about propagation of parameter uncertainties around 21:47.

A (possibly) quick question regarding this in DiffEqFlux.jl and neural DEs. Is it possible to get uncertainties from the neural DE part? Especially uncertainties around an ANN in issue [How to mix “normal” ODEs and Neuronal ODEs?](https://github.com/JuliaDiffEq/DiffEqFlux.jl/issues/15), when it is implemented.

Thanks!

Interesting question. Haven’t tried it. Let’s give it a try and get it working. In principle we could. Open an issue.

Feel free to ping me in case you need support on the `Measurements.jl` side 🙂
