greydanus / hamiltonian-nn Goto Github PK

Hi,
I read your paper and find the work you have done absolutly amazing. I am reading the github right now to fully understand how the "framework" works. But I have a little issue with the method rk4. Is it used for the estimation of the derivative of the hamiltonian? If it is the case what is the purpose behind computing the drivative that way.

Thanks in advance

Kia ora,

I don't understand the train method in ./experiment-2body/train.py. I've run the file and it saves the 2 body orbits predicted by the hnn, but nothing else.

How do I train the baseline model?

Nga mihi,

Matthew
