Manual Page For FFJORD

[prbzrg]

It would be great to have more documentations about FFJORD:

• [X] Straightforward tutorial
• [X] Constructor documentation
• [ ] Documentation for arguments
• • [ ] regularize
• • [ ] monte_carlo
• • [ ] e
• [ ] Documentation for methods
• • [ ] forward_ffjord
• • [ ] backward_ffjord

What should we add to the list?
