Hi,
1. What is a black box ode solver?
(It sounds like a proprietary tool but that doesn't make sense and googling didn't bring up anything useful)
2. Have you found any areas where there is a significant difference in the quality of the results using this method rather then the normal discrete method?
I am sorry if these questions are a bit bellow you, or if you already answered them in the paper.
- theSage 8y agoBlack box means you have no access to how a system actually does some task. All you know is that given an input the system will provide the output. ODE solver is an ordinary differential equation solver. For example [a] [a] : https://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.ode.html https://docs.scipy.org/doc/scipy/reference/generated/scipy.i...

But our follow-up paper, FFJORD [https://arxiv.org/abs/1810.01367 https://arxiv.org/abs/1810.01367] we used the continuous normalizing flows to get SOTA efficiently sample-able density models.
