@xavierjgonzalez Makes sense thanks! As always, it's curious/annoying that `jvp`s are essentially free but `jacrev`s are completely off the cards

[Xavier Gonzalez @xavierjgonzalez]

Fixed point iterations for parallelizing nonlinear dynamics is all the rage:
- Newton for RNNs
- Picard for diffusion models
- Jacobi for parallel decode of LLMs

But how do these techniques relate, and when should you use them?

We show you how in our new paper 🧵

@andreamichi @depthfirstlabs Open source ❤️
Safe open source ❤️❤️

[Max Welling @wellingmax]

@Sam_Duffield @HoldijkLars @iclr_conf @mmbronstein I am still thinking about that key equation too!

[Sam Duffield @Sam_Duffield]

I think we’ll all agree I dressed appropriately too 🇧🇷⚽️

[Sam Duffield @Sam_Duffield]

It was super fun to present my SDE decomposition at the @iclr_conf DeLTa workshop

And thanks for stopping by @wellingmax @mmbronstein, really enjoyed chatting and lots to think about!

#ICLR2026

[Lars Holdijk @HoldijkLars]

Did @wellingmax’s keynote at #iclr2026 leave you wanting more stochastic thermodynamics and generative AI?

Come join Max and me at poster #1023 in Pavilion 3 in the afternoon to chat about how we can learn escorted protocols for multistate free-energy estimation!

[Normal Computing 🧠🌡️ @NormalComputing]

Normal Computing is sponsoring @iclr_conf 2026 in Rio de Janeiro.

Our research team will be on-site presenting papers spanning thermodynamic computing, Normal's physics-based computing architecture, and the AI methods underpinning Normal EDA, our platform for silicon engineering.

Come talk to the researchers behind the work. We'll share a preview of what we're launching live at the conference. Follow along for real-time updates in the ICLR app.

Meet us at the booth:
Thursday, April 23 – Saturday, April 25
9:30 AM – 5:30 PM daily

[Sam Duffield @Sam_Duffield]

I'll be at ICLR this week 🇧🇷 presenting my complete SDE decomposition at the DeLTA workshop on Monday.

Reach out if you want to meet!

cuthbert is turning into a really awesome tool that's made our experience in writing dynestyx (https://t.co/279p5jB7vA) much more pleasant! Super happy to be seeing symbiosis between the two!

[Sam Duffield @Sam_Duffield]

There's a load of fun examples in the cuthbert docs and we're always looking to add more! 🐛

The ensemble Kalman filter has been added to cuthbert by @DanWaxmanML @BasisOrg 🔥

The EnKF is one of those algorithms that "just works" - oftentimes in settings it has no right to

[Sam Duffield @Sam_Duffield]

In this highly nonlinear example it's more accurate and faster than both extended and particle filters.

Love this, let's have the LLMs protect our code for us
