Originally, the goal of generative models was just to capture the distribution of the dataset. Since then, we've shifted to maximize human preference and vibe checks. This must have introduced biases and made the models worse, at least on some aspect, at modelling the data distribution.

I'm speaking at #aiPULSE2025 today on Open & re-purposable foundation models for the automotive industry. The morning keynotes talked a lot about open source so my slide here might be timely.

🛠️ Already have a complex, pre-trained pipeline? If you are using bilinear interpolation anywhere, NAF acts as a strict drop-in replacement. Just swap it in. No retraining required. It’s literally free points for your metrics.📈

That was a cool project brillantly led by Ellington Kirby during his internship. We were curious if we could train diffusion models on sets of point coordinates. For images, this is a step towards spatial diffusion, with pixels reorganizing themselves, instead of diffusing in rgb values space only.

Is it just me or is fucking linkedin taking over some of the functions that twitter used to fill?

🔥🔥🔥 CV Folks, I have some news! We're organizing a 1-day meeting in center Paris on June 6th before CVPR called CVPR@Paris (similar as NeurIPS@Paris) 🥐🍾🥖🍷 Registration is open (it's free) with priority given to authors of accepted papers: cvprinparis.github.io/CVPR2025InPa... Big 🧵👇 with details!

Wow, neet! Reannotation is key here. Conjecture: As we are get more and more well-aligned text-image data, it will become easier and easier to train models. This will allow us to explore both more streamlined and more exotic training recipes. More signals that exciting times are coming!

A game changer. A lot of people suspected it *should* work, but actually seeing it in action is something.

🚗 Ever wondered if an AI model could learn to drive just by watching YouTube? 🎥👀 We trained a 1.2B parameter model on 1,800+ hours of raw driving videos. No labels. No maps. Just pure observation. And it works! 🤯 🧵👇 [1/10]

Bluesky is less engaging because the algorithm is less predatory.

I'm curious who at Microsoft or OpenAI thought it was a good idea to publicize this narrative. If you are an organisation concered about ethics of training data, now is probably your best chance to act and be heard. www.reuters.com/technology/m...

The plateau on training scaling and the shift to test-time scaling created favorable conditions for a competitor like DeepSeek to raise and catch up with OpenAI. Nah, I just made that up. Need to put more thoughts into this. 🤔

We've reached a point where synthetic data is just better and more convenient than messy noisy web-crawled data. It's been true for multimodal data for a while, and semi-automated data as in the Florence-2 paper has been very succesful. arxiv.org/abs/2311.06242

Better VQ-VAEs with this one weird rotation trick! I missed this when it came out, but I love papers like this: a simple change to an already powerful technique, that significantly improves results without introducing complexity or hyperparameters.

Have you ever wondered how to train an autoregressive generative transformer on text and raw pixels, without a pretrained visual tokenizer (e.g. VQ-VAE)? We have been pondering this during summer and developed a new model: JetFormer 🌊🤖 arxiv.org/abs/2411.19722 A thread 👇 1/

For AI to be fair and sustainable, we'd need to figure out attribution, i.e. "How much does training sample X contribute to model output Y?" Then the creator of sample X gets paid an amount proportional to what the user paid for the inference call that produced output Y.

A great place for students interested in AI/CV research internship. It's a very strong team, invested with all of their students. Check it out.

ICYMI our PointBeV #CVPR2024 poster here's a quick talk by lead author Loïck Chambon. It brings a change of paradigm in multi-camera bird's-eye-view (BeV) segmentation via a flexible mechanism to produce sparse BeV points that can adapt to situation, task, compute www.linkedin.com/posts/andrei...

The Cosmos suite of neural tokenizers for images & videos is impressive. Cosmos is trained on diverse high-res imgs & long-vids, scales well for both discrete & continuous tokens, generalizes to multiple domains (robotics, driving, egocentric ...) & has excellent runtime github.com/NVIDIA/Cosmo...

This is ridiculous. And then people will talk about inclusivity and mental health. Sorry to speak my mind so openly, but this has to be the most toxic idea in a very long time.
