    As I was reading your comment I was thinking Physics Informed NN’s and then you went there. Nice. I agree.

    I’ve built some models that had a solution constrained loss functions—featureA must be between these values, etc. Not quite the same as defining boundary conditions for ODE/PDE solutions but in a way gets to a similar space. Also, ODE/PDE solutions tend to find local minima and short of changing the initial conditions there aren’t very many good ways of overcoming that. Deep learning approaches offer more stochasticity so converge to global solutions more readily (at the risk of overfitting).

    The convergence of these fields is exciting to watch.

      Yeah, thats a fair point and another appealing reason for DL based methods
