This isn't physics. It's curve fitting. If you want to do physics, start by having the code discover the underlying differential equation. Handy, though.

Rasmus Nordström2 years ago

ELI5 please, is this just brute forcing different formulas to see what fits that data or is it more magic to it?

Moritz Zaiss2 years ago

Nice, I love these approaches! A differentiable physicist that doesn't need coffee. Check out the work of @GMartius in this context!

Would it be more straightforward to optimize in frequency domain? Curious.

Luis Tobon2 years ago

Try Sindy.

From the latest episode with Ivan Poupyrev from Archetype AI The idea is simple but revolutionary: -- using sensor data, similar to how humans observe the physical world through our biological sensors -- to let machines 'talk' to the physical world. In the case of packages, this means not just knowing where it is, but what's happening to it in real-time.
