PULSE: Physics-based Universal humanoid motion Latent SpacE/Representation

Code: github.com/ZhengyiLuo/PUL…
Site: zhengyiluo.com/PULSE
Paper: arxiv.org/abs/2310.04582

As a motion representation, PULSE is low dimensional (32), high coverage (99.8% of…

Back in the lab this week updating Kinetic Diffusion, our AI powered dance performance, with new Stable Foundation models. Speed and pixels have increased tremendously unlocking new opportunities. Here’s an experiment in “popping” new prompts in with connection to the movement ⬇️

While I am at it, also releasing the trained models for VR controllers tracking using PHC.

This task is a essentially a generalized version of motion imitation, where there are only 3 6DOF points to track (red dots) instead of 24.

Models are released at…

2023 was a wild year for technological progress. At Meta, our two biggest long-term bets on the technologies of the future both make great leaps forward but more excitingly, they began to converge. I wrote about it here: meta.com/blog/quest/boz…

PHC will be presented at

📍Location: Room 'Foyer Sud' - 101
⏰ Thursday 5th 10:30 AM-12:30 PM
🆔: 1900

Humanoid control for avatars, motion imitation on AMASS, and fall-state recovery during imitation.

Jinkun Cao will be there to present🎉🎉🎉 (no visa for me🥲)

Here's my conversation with Mark Zuckerberg, his 3rd time on the podcast, but this time we talked in the Metaverse as photorealistic avatars. This was one of the most incredible experiences of my life. It really felt like we were talking in-person, but we were miles apart 🤯 It's…

This is huge: Llama-v2 is open source, with a license that authorizes commercial use!

This is going to change the landscape of the LLM market.
Llama-v2 is available on Microsoft Azure and will be available on AWS, Hugging Face and other providers

Pretrained and fine-tuned…
