An implementation of a simple Social Force model in JAX + Diffrax as well as a differentiable density-based optimisation of the parameters with Optax or numpyro.

To run the code in this repo, install the poetry package manager, navigate to the folder, and run poetry install. This will install all dependencies.

Note: The local file imports are kinda messed up for this repo, you may need to play around with the path to get it working properly.

• The wall force sometimes lets pedestrians escape (see animation), oops.
