DNA origami is already a crazy enough rabbit hole x.com/jwt0625/status…
Found a new rabbit hole called DNA origami, and these are some of the fanciest stuff I've seen in a while: A mouse trap but for virus? A sub 100 nm turbine that could dock into a nanopore? A DNA rotary ratchet motor driven by an AC voltage up to 250 rpm?? Not sure how practical…
Bird saves and reproduces data: A PNG image of a bird ( photo of a bird -> spectral synthesizer ) was reproduced by an adult Starling bird youtu.be/hCQCP-5g5bo?si…. It seems to have reproduced the sound in conjunction with some additional notes which made it not detectable…
MIT's AlterEgo is a wearable device that lets you silently talk to a computer—without speaking aloud. Tests got to something like. Most active 2018. Some new possibilities exist today. It reads neuromuscular signals from your jaw + face during internal speech and turns them…
Beautiful @GoogleResearch paper. LLMs can learn in context from examples in the prompt, can pick up new patterns while answering, yet their stored weights never change. That behavior looks impossible if learning always means gradient descent. The mechanisms through which this…
New video on the details of diffusion models: youtu.be/iv-5mZ_9CPY Produced by @welchlabs, this is the first in a small series of 3b1b this summer. I enjoyed providing editorial feedback throughout the last several months, and couldn't be happier with the result.
Climate controlled tent. 10' x 8' x 7.2' Solar as emergency power for car & cooking / starlink supply, works great. 2 min setup/teardown. Upgrading the solar is the next step. Probably building a mount for it to charge the buffer battery while driving. Tent fits in frunk.
Our paper aims to answer two questions: 1. What's the difference between prediction and world models? 2. Are there straightforward metrics that can test this distinction? Our paper is about AI. But it's helpful to go back 400 years to answer these questions.
So this blew up. Probs good to add clarification to @DimaKrotov's quote "Computation is a physical process. We can study the flow of bits just as we study the flow of atoms" This has always been the perspective of Hopfield Nets. Buckle up here's a primer on Associative Memory🧵
Never stop being a proud physicist @DimaKrotov , it's a pleasure working with you 🥳. research.ibm.com/blog/dmitry-kr… "Computation is a physical process. We can study the flow of bits just as we study the flow of atoms" More juicy Dima snippets in 🧵

Excited to share Energy-Based Transformers (EBTs), which allows you to implement system 2 thinking in any modality! EBTs formulate reasoning as an energy optimization problem, allowing models to internally think without complexities like CoT or multiple recurrent latents.
How can we unlock generalized reasoning? ⚡️Introducing Energy-Based Transformers (EBTs), an approach that out-scales (feed-forward) transformers and unlocks generalized reasoning/thinking on any modality/problem without rewards. TLDR: - EBTs are the first model to outscale the…
