This sounds interesting. Would you mind sharing how exactly you have this setup?

Of course sine can appear in the solution for dynamical systems but the function itself is not dynamical. When evaluating sin(x) you do not need to know about the previous state.

Edit: should not be approximated

Comment #31213905
Periodic function like sin(x) are not a dynamical system so its previous state does not determine the current state. So it should be approximated in that way.

Not MLP, but PySindy[0] might be a way to find a closed form solution. A simple MLP may not be best way to achieve what are you are after. [0] https://github.com/dynamicslab/pysind…

This does not appear to be the usual approach of training the neural network on tons of data from the physics simulation. Instead they use the actual physics equations to form the …

That really resonated with me. I basically stopped using Twitter because of the reasons you outlined here. This tool, however, might make Twitter useful again for me!

There has been lost of theories to explain how jets from black hole systems form. New observations of light polarization from M87 jet show twisting magnetic field lines which sugge…

That's just one of the jets. In fact, I think only one side is observable as it pointed close to our direction, making the other side very difficult to observe.

Not all vaccines work the same way and it is not obvious what the long term impact of such a "flu pill" would be on our immune system. For example, I would like to know what would …

It depends on what you are doing. If it is numerical work with matrix operations, then Fortran is fast and pretty intuitive. Some of the annoyances come from dealing with legacy co…

Regarding dynamical systems, Neural ODEs hold promise as they are more analogous to the numerical solvers. I think with any dynamical system, purely data driven approach can be pro…

Yes, they would gain mass from feeding but not get 40% bigger while still in that binary configuration. So it seems these BHs start out bigger than previously assumed.
