How to learn an autonomous system with DeepXDE.

[rispolivc]

Hi guys, I'd like to ask for a tip. I have a experimental dataset $(t_i, \mathbf{x}_i)$, $i\in{1,\ldots,N},$ that is modeled through a autonomous system of the form $\dot{\mathbf{x}}(t)=f(\mathbf{x}(t))$, where $f$ is an unknown function. So, I'd like to use DeepXDE to both learn $f$, through a neural network, and then solve the PINN problem for $\mathbf{x}(t)$. I don't know how to learn both things all at once with DeepXDE. Any suggestions? I appreciate.
