  • [P] Optimistix, nonlinear optimisation in JAX+Equinox!
    3 projects | /r/MachineLearning | 14 Oct 2023
    Optimistix has high-level APIs for minimisation, least-squares, root-finding, and fixed-point iteration and was written to take care of these kinds of subroutines in Diffrax.

    Diffrax (https://github.com/patrick-kidger/diffrax).

    Here is the GitHub: https://github.com/patrick-kidger/optimistix

    The elevator pitch is Optimistix is really fast, especially to compile. It

  • Scientific computing in JAX

    Sure. So I've got some PyTorch benchmarks here. The main take-away so far has been that for a neural ODE, the backward pass takes about 50% longer in PyTorch, and the forward (inference) pass takes an incredible 100x longer.
  • [D] JAX vs PyTorch in 2023
    5 projects | /r/MachineLearning | 9 Mar 2023
    FWIW this worked for me. :D My full-time job is now writing JAX libraries at Google. Equinox for neural networks, Diffrax for differential equation solvers, etc.
  • Returning to snake's nest after a long journey, any major advances in python for science ?

    It's relatively early days yet, but JAX is in the process of developing its nascent scientific computing / scientific machine learning ecosystem. Mostly because of its strong autodifferentiation capabilities, excellent JIT compiler etc. (E.g. to show off one of my own projects, Diffrax is the library of diffeq solvers for JAX.)

  • PyTorch 2.0
    4 projects | news.ycombinator.com | 2 Dec 2022
    At least prior to this announcement: JAX was much faster than PyTorch for differentiable physics. (Better JIT compiler; reduced Python-level overhead.)

    E.g for numerical ODE simulation, I've found that Diffrax (https://github.com/patrick-kidger/diffrax) is ~100 times faster than torchdiffeq on the forward pass. The backward pass is much closer, and for this Diffrax is about 1.5 times faster.

    It remains to be seen how PyTorch 2.0 will compare, or course!

    Right now my job is actually building out the scientific computing ecosystem in JAX, so feel free to ping me with any other questions.

  • Python 3.11 is much faster than 3.8

    Which are neural network and differential equation libraries for JAX.

    8 projects | news.ycombinator.com | 15 Oct 2022
    Autodifferentiable programming!

    Neural networks are the famous example of this, of course -- but this can be extended to all of scientific computing. ODE/SDE solvers, root-finding algorithms, LQP, molecular dynamics, ...

    These days I'm doing all my work in JAX. (E.g. see Equinox or Diffrax: https://github.com/patrick-kidger/equinox, https://github.com/patrick-kidger/diffrax). A lot of modern work is now based around hybridising such techniques with neural networks.

    I'd really encourage anyone interested to learn how JAX works under-the-hood as well. (Look up "autodidax") Lots of clever/novel ideas in its design.
