Neural Networks for Physics Simulation: A JAX and Neural ODE Guide
A detailed hands-on guide to differential equations has been published for Diffrax and JAX. It shows how to set up a stack with JAX, Equinox and Optax, solve ODEs with adaptive solvers, run batched simulations with vmap, and build a neural ODE that learns from synthetic data of a physical system. It also includes a separate SDE example using VirtualBrownianTree and a JIT benchmark of the solver.

A hands-on guide has been released on using neural networks to solve differential equations, from installing JAX and Diffrax to building and training neural ODE models, with complete working code.
Which libraries do you need to train neural networks on differential equations?
The guide uses numpy, jax, jaxlib, diffrax, equinox, optax and matplotlib to produce a reproducible working notebook without dependency conflicts.
What are neural networks for physics simulation used for?
Neural ODEs make it possible to build trainable models of differential equations. The guide combines ordinary and stochastic differential equations into a single pipeline for scientific computing in Python.
How do you get started with JAX and Diffrax?
The guide starts by setting up a clean computing environment with numpy, jax, jaxlib, diffrax, equinox, optax and matplotlib, to avoid conflicts and get reproducible results.
