We’ve been making phylogenetic trees differentiable :)
Check out our work at #ICML2023 workshops - Sampling and Optimization in Discrete Space (SODS) ፨ and Differentiable Almost Everything (DiffAE) 〆
Looking forward to discuss and learn more! 🙌
❤️ work with Avi & @sokrypton

investing time to learn from a cool paper 🔥, @labmlai style by @vpj and team github.com/vpj/annotated_imp….
worth integrating into my dev workflow — using AI to implement/move faster while still investing time to genuinely understand the underlying ideas.
Last year I trained the advantage-conditioned VLA for π*0.6 during my internship @physical_int. Now, I have a much improved recipe.
Introducing ✨Advantage Guidance✨, a performant RL method with stable advantage-conditioned supervised training and contrastive guidance sampling

Colchicine is a toxic alkaloid found in some lily species, however this deadly poison can also be used in molecular biology labs or as a medicine for gout

My browser port of 3Blue1Brown's manim had 12,952 npm downloads last month. It's open source

A step change in protein design: RFD4-Proteina is enables everyone today.
We partenered with @huggingface to make available a free space.
You can solve your hardest biology problem right now. No CS degree required: huggingface.co/blog/nvidia/r…
More to come...
Avengers assemble: 1 year BakerLab + NVIDIA GenAIR = 🔥 rfd4-proteina.org
Presenting RFD4-Proteina, our latest protein design model, significantly better and faster than everything we compared against, both in silico and in the lab! 1/30

This is so dope. I'm so happy to see that my tool is useful
did a group presentation today with @3blue1brown's manim style transitions. Sharing the template for anyone to build upon

For some reason the word tpu “chip” makes me feel like its tiny compared to nvidia gpus 😆
Been playing with v6e chips lately and pretty impressed

Excited to share the final paper of my PhD! Driven by challenges in modeling large systems biology models with diffusion transformers, we developed a framework to overcome difficulties in 1) compositional sampling, 2) hierarchical sampling and 3) the sim-2-real gap 🤖 ↔️ 🌍

Anyone have access to free AMD gpus they aren't using? Was gonna try test some ported methods but dont have access to any AMD gpus to test on.

People are prophecying the death of math but actually in the last few months is the first time that I have even started thinking about hiring a math PhD as a postdoc, because the prospects of doing advanced math in my area are so much brighter now.

as a chat goes, Opus 5 keeps on saying

In collaboration with the @francesarnold and @pengliu_group research groups, we @GoogleDeepMind are proud to release AlphaProtein Novo, a pipeline for small-molecule enzyme design.
We developed AlphaProtein Novo on a few standard model reactions, and validated designs in our own wet lab. We then wanted to challenge this system against nascent chemistries, so we asked leading scientists in biocatalysis whether we could partner on the reactions they cared about.
