🚨 Deadline Extension Instance-Level Recognition and Generation (ILR+G) Workshop at ICCV2025 @iccv.bsky.social 📅 new deadline: June 26, 2025 (23:59 AoE) 📄 paper submission: cmt3.research.microsoft.com/ILRnG2025 🌐 ILR+G website: ilr-workshop.github.io/ICCVW2025/ #ICCV2025 #ComputerVision #AI

Our remote sensing foundation model Galileo has been accepted to ICML 2025! Galileo outperforms state-of-the-art across different input data modalities and shapes, and using it requires only minimal data and compute. More at: arxiv.org/abs/2502.09356

Can you train a performant language model using only openly licensed text? We are thrilled to announce the Common Pile v0.1, an 8TB dataset of openly licensed and public domain text. We train 7B models for 1T and 2T tokens and match the performance similar models like LLaMA 1 & 2

We will be presenting the 🍄 FungiTastic 🍄, a multimodal, highly challenging dataset and benchmark covering many ML problems at @fgvcworkshop.bsky.social CVPR-W on Wednesday! ⏱️ 16:15 📍104 E, Level 1 📸 www.kaggle.com/datasets/pic... 📃 arxiv.org/abs/2408.13632 @cvprconference.bsky.social

#KostasThoughts: As an AC, it’s frustrating when reviewers only see the rebuttal through the lens of their own review. Step back—consider all reviews and discussions. DON’T rush to finalize; see the FULL picture!

#KostasThoughts: There is no shame getting the initial review wrong, e.g., by missing an important detail. It is wrong when you let your ego get in the way of arriving at the correct decision.

VRG from CTU in Prague has 9 of its members listed as outstanding reviewers. Congratulations to @gkordo.bsky.social, @billpsomas.bsky.social , @stojnicv.xyz , Pavel Suma, @ducha-aiki.bsky.social , Miroslav Purkrábek, Tomas Vojir, and Yaqing Ding.

NeurIPS'25 (abs): 4 days + 2h. NeurIPS'25 (paper): 8 days + 2h.

We are back at #ICCV2025 for the second workshop on Hyperbolic and Hyperspherical Learning for Computer Vision. We will have 2 tracks: one for new research (to be published in proceedings) and one for recently published works. Deadline: June 1st Link: sites.google.com/view/beyonde...

Have you ever wondered what makes two models different? We all know the ViT-Large performs better than the Resnet-50, but what visual concepts drive this difference? Our new ICLR 2025 paper addresses this question! nkondapa.github.io/rsvc-page/

The Greeks 🇬🇷 in #AI Symposium aims to bring together researchers from #AI, #ML, #ComputerVision, #Robotics, #Neuroscience, & related fields to share their latest research. There are no proceedings, allowing authors to present their already published work to a broader audience. www.greeksin.ai

Exciting News! Shoutout to @hf.co 🤗 for hosting ILIAS in its full scale! You can now easily download it via: huggingface.co/datasets/vrg... This marks a milestone in i2i and t2i retrieval, paving the way for significant advancements in the field. Huge thanks to @hf.co team for their support!

The Visual Recognition Group at CTU in Prague organizes the 49th Pattern Recognition and Computer Vision Colloquium with D. Karatzas, M. Masana, T. Tommasi, P. Mettes @pascalmettes.bsky.social , E. Brachmann @ericbrachmann.bsky.social and V. Stojnic @stojnicv.xyz cmp.felk.cvut.cz/colloquium/#...

ILIAS is a large-scale test dataset for evaluation on Instance-Level Image retrieval At Scale. It is designed to support future research in image-to-image and text-to-image retrieval for particular objects and serves as a benchmark for evaluating foundation models and retrieval techniques.

1/n🚀If you’re working on generative image modeling, check out our latest work! We introduce EQ-VAE, a simple yet powerful regularization approach that makes latent representations equivariant to spatial transformations, leading to smoother latents and better generative models.👇

🚀Exciting news🚀 I’ve been awarded the Marie Skłodowska-Curie Postdoctoral Fellowship (#MCSA-PF) 2024 with 98/100!🎉 🥟My project, RAVIOLI, hosted at CTU in Prague, under @gtolias.bsky.social, integrates retrieval-augmented predictions into vision-language models for open-vocabulary segmentation.

For PhD and MSc students interested in a research visit to Prague/VRG in 2025: we're open to hosting short-term collaborations or internships on a range of computer vision topics. If this sounds exciting, reach out by e-mail! We'd love to discuss potential projects. Some examples 🧵 #Internship #CV

A late introduction: I am an Associate Professor at CTU in Prague and a computer vision researcher at the Visual Recognition Group (VRG - vrg.fel.cvut.cz). VRG consists of about 40 members and I am leading a small team within VRG. I am made in Greece and exported to France + Czech Republic 🧵⬇️

Image Matching Workshop is accepted to #CVPR2025. You know the drill - we will have IMC challenge, papers and invited talks, all as usual. P.S. Website will be updated later image-matching-workshop.github.io @atabb.bsky.social @cvprconference.bsky.social

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

From @fchollet.bsky.social over on the other site. "they demand serious scientific attention" -- indeed! But how to do science on these results without more openness?

It blows my mind that NASA is able to receive data from 4.67 billion miles away, but I lose Wi-Fi signal in my kitchen.

Our starter pack 🎉

Here are my thoughts about Bluesky based on a couple weeks of experience using it. tl;dr: very, very impressive

🆕 Submit a “highly irresponsible” #CVPR2025 review, your paper submissions will be desk rejected. More info: cvpr.thecvf.com/Conferences/...

Someone called this mass exodus from Twitter ‘the fall of the Broman Empire’ and I died laughing. 💀

Great opportunity 👌🏽👌🏽👌🏽

Whenever AI "generates" something impressive, the first question we should always ask is: "What does the closest sample in the training data look like?" LLMs are amazing interfaces for accessing the world's information but they need to be treated as the "search and synthesis" tools they are.

Bsky has strong "getting the band back together" vibes...

6 years ago, in the days of GAN art, I wrote an article called "Can Computers Create Art?", arguing that computers should not be considered artists, regardless of how good image generation gets. People sometimes ask if my views have changed. I say, 1/🧵 www.mdpi.com/2076-0752/7/...
