I think it's overly optimistic with the timing. I'm waiting for the last step anytime now 😬

Guys, I don't think we have the same definition of "outstanding"...

I nearly missed the time when the trees in front of the lab turned red! But here there are, with a different viewpoint than usual 🍂🍁

Also, pretty image! The website for the project is gorgeous, check it out: arijit-hub.github.io/projects/din... Code and models are available: github.com/arijit-hub/d...

If you sample from a fixed DINO feature, you can do DINO inversion. Not sure how useful this is, but it's neat nonetheless because it show that the self-condition can be used to steer the generation process

Doing so is much faster than the other uses of a pretrained feature extractor, and leads to a massive improvement compared to the baseline (i.e., without DINO) both in latent and pixel flow-matching.

During Sampling, you start with the usual Gaussian noise for the image and zeros for the self-condition, and then you rollout the predicted DINO to the next sampling step The predicted features are fairly stable and act like an anchor guiding the image ODE

The training is also very simple and is similar to the self-conditioning in RIN (Jabri ICML'23). You do a 1st forward with 0, get your predicted DINO features (detached) and pass them as additional condition to the 2nd forward+backward pass Since there is only 1 ODE, there is only 1 noise schedule

What a weird acknowledgment. I've seen companies doing that in the past, but that's a first for a theoretical CS paper by academics. I don't think there is any opinion in that paper. Is it because of Anthropic? (paper: arxiv.org/abs/2506.07977 lowers the complexity of 3SUM and related problems)

outlook (the webapp) is just unusable. It has more bugs than a first year student's assignment. How is this company valued trillions of $? I just cannot understand that. It's pure crap. the worst email app I've ever used, and I used to host my own webmail...

Drag'n drop figures for illustrating 1-NN. This would take so long without an LLM, I would not do it. I'm like a kid in a candy store with these interactive figures. I like interactive demos soooo much.

Guys, do you have the slightest idea who you are sending this to? I know I have a common name, but I'm pretty sure an LLM would not have included me in the list of recipients after only 1 google search.

This sentence is terrifying for any institutional organisation relying on this company. It should break immediately many many contracts with somewhat important information.

Let's try this. The table is actually split in 2 separated by close to a meter and the camera is positioned to make it appear seamless.

So apparently our roof has become a tinder hotspot for black redstart (rougequeue noir en français). They're very noisy during court, it seems. Surprisingly curious too.

Spam complètement invraisemblable reçu ce matin 💀 Comment peut-on en 2026 1) écrire ce genre de foutaises de boomers au moment où le pays prend en pleine poire la réalité du climat qu'il a construit, 2) avoir le culot de l'envoyer à un chercheur d'une école du ministère de la transition écologique ?

Sur la question du pourquoi les gens et les gouvernements successifs ne prennent pas les décisions qui s'imposent, je rappelle que cet article à presque 20 ans : www.pnas.org/doi/10.1073/... La réponse est alors claire : un égoïsme important doublé d'un niveau catastrophique en calcul de proba.
