"It is beautiful. It is elegant. Does it work well in practice? Not really. This is often the caveat we face in research: the things that are beautiful don't work and the things that work are not beautiful." – Daniel Cremers

"As roboticists and computer vision people [outside of big tech], do we have to just wait for the next foundation model?" I share the frustration. It's disempowering when most major progress recently is downstream of "foundation models" that you don't have the compute or data to train yourself.

Sort of, but DINOv3 also seems to (inadvertently?) point towards the limits of pure scaling. x.com/chrisoffner3...

Yay, DINOv3 is out! SigLIP (VLMs) and DINO are two competing paradigms for image encoders. My intuition is that joint vision-language modeling works great for semantic problems but may be too coarse for geometry problems like SfM or SLAM. Most animals navigate 3D space perfectly without language.

When I try it, it messes up the image on the very first try, creating a vertically repeating image. If I then crop it and try a second time, it refuses. 🤷‍♂️

What does this “€ 178,347 Monthly Contribution” count? Does this include the corporate memberships? Because that is very little money to support software development.

How about (b) + use the LiDAR data to parametrize 3D scenes that are physically simulated/rendered and further randomized/adapted using generative AI, then train on both captured and this derived 3D synthetic data?

The NYU website was hacked and replaced with a graph claiming to show the SAT scores of admitted students broken down by race. Right-wingers celebrate this to show that DEI was racial discrimination, left-wingers say the graph is racist and fake. Does anybody know if the numbers are real or fake?

Currently yes, but the blog post argues that this is not a fundamental limitation of the algorithm but one of our current hardware.

Chris Offner @chrisoffner3d.bsky.social · 22/03/2025

Instead of thinking about the raw numbers of operations an algorithm performs, the work-depth model thinks about the depth of the computation graph with respect to the input size, i.e. the minimum number of non-parallelizable sequential operations. supaiku.com/attention-is...
