Really excited to share our recent work on using AI to control an electron microscope to rearrange individual atoms! This was a really fun collaboration between @GoogleDeepMind, @Mila_Quebec, and @ORNL. paper: 1/5 arxiv.org/abs/2311.17894…
Controlling matter at the level of individual atoms could be an extremely powerful capability. While possible by humans via careful manual control of an electron microscope, AI can be used to automate this process, increasing throughput, and making it less error-prone. 2/5

An attempt at unabridged translation of Zelensky's address to Russian citizens:
“…And now in Russian language. Today, I initiated a phone call with the president of the Russian Federation. Result: silence. But the silence should have been over Donbas. That’s why today I want to address the citizens of Russia. Not as a president, but as a Ukrainian citizen.

Can RL algorithms be replaced with transformer-based language models? We’ve looked at this question with our work on Decision Transformer:
1/8
Decision Transformer is just a GPT model conditioned on desired returns. Returns, states and actions are fed into the model like tokens in a sentence (trajectory).
At evaluation time, specify the desired episode return and sequentially sample actions to get your policy.
