Looking for an RL algorithm for your video diffusion model? Worried about reward hacking? DDRL might be what you are looking for. Give it a try.
🤔Want a principled way to RL your diffusion model? Check Data-regularized Reinforcement Learning (DDRL)! Post-train @nvidia #Cosmos World Foundation models with a million GPU hours! 🤯 Novel formulation ➡️ Theoretically integrates SFT into RL ➡️ Robust to Reward Hacking 🛑

I told my parents that I’d like to drop out of my cs phd program at Stanford a few months back. They didn’t let me, we’re asian :) So I graduated and started @moonlake_ai. @sharonal_lee and I saw urgency, and opportunities. Excited to share that we raised a 28 million dollar
We raised $28M seed from Threshold Ventures, AIX Ventures, and NVentures (Nvidia's venture capital arm) —alongside 10+ unicorn founders and top AI researchers— to build reasoning models that generate real-time simulations and games. Models are bottlenecked by practical

Hi, I'm now available for consulting or full-time. If your team is looking for a tech leader with lots of experience in Generative AI R&D, 3D, GPUs, etc -- or if you're looking for a CEO or CTO for a very early stage startup -- I might be your guy.

Thanks Xubo, I wish we had gotten to work longer together… best of luck with your next adventure!
Today is my last day at @StabilityAI . It’s incredible how quickly the past year has flown by! I’m deeply grateful for the opportunity to work alongside such talented and inspiring colleagues. A special thank you to Christian @chrlaf for trusting me to lead the speech research

As a senior researcher who has both published in A* venues and has written toolkits himself and overseen the development of several others, it is humiliating to have to do leetcode grinding for a research scientist role in big tech. I have written more code than most people and I

And that fixed things right up for me! Here is the code: https://t.co/0xipawlHyM

@3scorciav Perhaps, but this blue place works already a lot better than mastodon ever did. I created the account a couple of months ago, and when I went back yesterday found 1000 new followers, and lots of discussions. Will now be active there. It's enough for me.

I am also at the other place, the good place. The blue one. Same handle. Will see how this works out.

To be frank, the free world will not be led by the US anymore.
Europeans need to be frank: The "free world" will be led by a convicted felon & demagogue who doesn’t share our values but wants to destroy them. Liberal democracy is in peril. Is Europe prepared? No. Can it be & will we see real 🇪🇺 leadership we desperately need ? Hopefully!
