Everyone says they want general-purpose robots. We actually mean it — and we’ll make it weird, creative, and fun along the way 😎 Recruiting PhD students to work on Computer Vision and Robotics @umdcs for Fall 2026 in the beautiful city of Washington DC!

Zero123 can now generate 3D assets in 2 minutes with Gaussian Splatting thanks to amazing work done by Jiaxiang Tang et. al.!! Production-ready 3D generation is getting closer and closer👏 dreamgaussian.github.io

Introducing Dr. Robot, a robot self-model which is differentiable from its visual appearance to its control parameters. With it, we can control and plan robot actions through image gradients. Accepted to CoRL 2024 with an oral! drrobot.cs.columbia.edu

How can a visuomotor policy learn from internet videos? We introduce Dreamitate, where a robot uses a fine-tuned video diffusion model to dream the future (top) and imitate the dream to accomplish a task (bottom). website: dreamitate.cs.columbia.edu paper: arxiv.org/abs/2406.16862

Some naive thoughts about careers of AI researchers as a young uninformed PhD student 💭 An AI researcher has basically the same job as a film director. The three things you care about the most are: creativity, impact, and reputation. (1/n)

What I love about research is you never lose anything. For any project regardless of its outcome, if you: 1. had fun, 2. learned something, then I'd call that a victory! If it happened to make some impact in the field, even better!

Humans can design tools to solve various real-world tasks, and so should embodied agents. We introduce PaperBot, a framework for learning to create and utilize paper-based tools directly in the real world. paperbot.cs.columbia.edu

Do you know humans are infrared light bulbs💡? Excited to share our #CVPR2023 paper! With a thermal camera, we leverage “invisible reflections” created by the infrared radiation of humans in order to reconstruct their location, orientation, and 3D pose. thermal.cs.columbia.edu

What Fei-Fei is trying to say is PhD students at universities produce open-source, trustworthy AI research rather than closed-source, profit-driven business products so please invest in us poor but talented PhD students and we will make the best use of them for our society.

Fei-Fei Li says Stanford's Natural Language computing lab has only 64 GPUs and academia is "falling off a cliff" relative to industry

Nothing makes a PhD student more satisfied than a fully power-utilized 8-GPU server🔥

I hear arrogance, ignorance, and nonchalance. Let’s try to stop those attitudes as a research community.
