Key Points

  • The article is a hands-on tutorial explaining how to use Equinox, a lightweight neural network library built on JAX.
  • It highlights how eqx.Module represents models as PyTrees, making parameter handling, transformations, and serialization more explicit and straightforward.
  • The tutorial covers static fields and filtered transformations to control what parts of a model are transformed during training workflows.
  • It also explains how to work with stateful layers and connect everything into end-to-end training workflows.
  • Overall, the focus is on practical implementation patterns for building and training neural networks effectively in JAX using Equinox.

In this tutorial, we explore Equinox, a lightweight and elegant neural network library built on JAX, and show how to use it. We begin by understanding how eqx.Module treats models as PyTrees, which makes parameter handling, transformation, and serialization feel simple and explicit. As we move forward, we work through static fields, filtered transformations such […]
