Perplexity Cannot Always Tell Right from Wrong Perplexity -- a function measuring a model's overall level of "surprise" when encountering a particular output -- has gained significant traction in recent years, both as a loss function and as a simp...

Bluesky doesn’t really shine yet as a place to discover papers, especially at the intersection of biology and ML. To help a little, I’m going to start sharing papers I find interesting. To kick things off, here’s one from @petar-v.bsky.social and colleagues at DeepMind

We introduce MIRO: a new paradigm for T2I model alignment integrating reward conditioning into pretraining, eliminating the need for separate fine-tuning/RL stages. This single-stage approach offers unprecedented efficiency and control.

- 19x faster convergence ⚡
- 370x less FLOPS than FLUX-dev 📉

Did you open-source your #ICCV2025 works?

As a PyTorch Ambassador, I would like to write an article to introduce open-sourced ICCV 2025 works (including workshops and demos) for promoting open-source/science + PyTorch

If interested, share your work via the form in my reply 👇

I love the #eurips initiative! But to live up to its potential, it should be accepted an official #neurips conference location (similar to Mexico City) and not just an addon! Then we would save C02, rather than adding to it!!! What can we do to achieve this?

Probably because #NeurIPS2025 reviews were out, I saw some discussions on author-reviewer duties in ML/CV/NLP communities and complaints based on some common misinformation

Currently, CVPR, ICCV, and WACV require all *qualified* authors to serve as reviewers, NOT all authors

We've released code for integrating Gaussian Splatting with PyTorchGeoNodes — enabling procedural Gaussian Splatting!
This allows interpretable 3D reconstructions with better handling of occlusion, noise, and symmetry. Edit splats by tweaking program parameters.

I am heartbroken that I am not at the conference, but seeing what the government is doing to its people and the world, I simply couldn't go there.

I think we did a pretty good job with my amazing #CVPR2025 fellow PCs. With a lot of efforts, and thanks to the hard work of reviewers, ACs, and SACs, the review quality increased while we had to handle a steadily increasing number of submissions.

Philip Isola (seen wearing a blue shirt), who is the CVPR 2025 Program Co-Chair, says "One of the big trends this year in commercial chatbots is they've become multimodal; they now analyze and generate not just text but also images and sometime videos. On the horizon is the ability to generate complete interactive worlds. The image, video, and world synthesis methods being presented at CVPR are paving the way toward this kind of technology." On the bottom right there's a logo of the CVF/ IEEE Computer Society.

#CVPR2025 had a 13% rise in paper submissions--13,008 papers, 40,000+ authors. The technical program chairs say it’s courtesy of the #AI explosion & emerging image, video, and world synthesis methods, among other trends. cvpr.thecvf.com/Conferences/...

There is some discussion of having a satellite location for NEURIPS 25 outside the US but in a similar time zone. Folks are studying the feasibility and trying to guess how many people would go there
