There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd. It's not just budgets but research, institutions, expertise, and training the next generation.

I know this look well. It’s the same one I get when I introduce the Fourier transform in my computer vision course to the CS crowd.

Aria Gen 2 is very impressive, with fully onboard SLAM and various other perception all within a 75g device with an hours-long battery life. Processing on custom silicon. Congrats to the Reality Labs team.

We've built a simulated driving agent that we trained on 1.6 billion km of driving with no human data. It is SOTA on every planning benchmark we tried. In self-play, it goes 20 years between collisions.

Video Depth Anything: Consistent Depth Estimation for Super-Long Videos TL;DR: Long videos support; Depth Anything V2 with efficient spatial-temporal head. Temporal consistency loss -> depth gradient (no geometric priors)

100 years ago today, #OTD in 1925, Edwin Hubble announced that Andromeda and other spiral nebulae were definitely separate galaxies outside the Milky Way, in a paper read to an AAS meeting by H.N. Russell. There was no doubt that the Universe was more than just our little island of stars. 🧪 🔭 ⚛️

Introducing 👀Stereo4D👀 A method for mining 4D from internet stereo videos. It enables large-scale, high-quality, dynamic, metric 3D reconstructions, with camera poses and long-term 3D motion trajectories. We used Stereo4D to make a dataset of over 100k real-world 4D scenes.

Back in college I took a developmental biology class. This field has come so far with advancing technologies like light sheet microscopy. This video is just plain amazing.

Zhengqi led a really nice new paper that computes really nice camera poses and depth maps from everyday videos, not just the standard SLAM-mable sorts of videos you often see. It's really fast and robust, and I think it's quite neat.

A common question nowadays: Which is better, diffusion or flow matching? 🤔 Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably.
