One particular area of scientific interest is the setting of inverse problems, where one knows the forward dynamics of a system are described by a partial differential equation and the task is to infer properties of the system given (potentially noisy) observations of these dynamics.

Given samples of solutions $x(t)$ to an unknown dynamical system $\dot{x}(t)=f(t, x(t))$, we approximate the function $f$ using an ensemble of neural networks.
