Exciting updates on Project GR00T! We discover a systematic way to scale up robot data, tackling the most painful pain point in robotics. The idea is simple: human collects demonstration on a real robot, and we multiply that data 1000x or more in simulation. Let’s break it down:

🔥Excited to share our work on speculative diffusion decoding! We use discrete diffusion as a drafting model to massively speed up #LLM inference---up to 8.7x faster over standard generation and 2.5x faster than traditional spec dec approaches.🚀 🔗Links below

1/3 Today, an anecdote shared by an invited speaker at #NeurIPS2024 left many Chinese scholars, myself included, feeling uncomfortable. As a community, I believe we should take a moment to reflect on why such remarks in public discourse can be offensive and harmful.

Some further thoughts on the idea of "thinking with images": 1) zero-shot tool use is limited -- you can’t just call an object detector to do visual search. That’s why approaches like VisProg/ViperGPT/Visual-sketchpad will not generalize or scale well. 2) visual search needs to

Can diffusion models appear to be learning, when they’re actually just memorizing the training data? We show and investigate this phenomenon in the context of neural network weight generation, in our recent paper “Generative Modeling of Weights: Generalization or Memorization?"
