🚀 Yesterday we held the fourth session of our Seminar Series! 🧠Prof. @PascalMettes delivered a talk on "Hyperbolic Deep Learning" He explained that hyperbolic geometry is especially suited for hierarchical deep learning, offering better accuracy with fewer dimensions.

Starting now! Leveraging context in prototypes for learning representations. Come find out more! 📍East Exhibition Hall A-B #E-2406

SSL, in particular, CL, relies more and more on prototypes (learnable representations that hold some group meaning) But! overclustering, enforcing equipartitions, and underrepresentation are still problems that plague the prototypes We solve them with our method: SOP

Want the best possible embeddings in hyperbolic space while still maintaining GPU compatibility? Check out our #ICML2025 poster! We show how to minimize distortion and get more precision with hyperbolic floating point expansions. #1 method for embedding any tree-like structure.

After a very successful 1st edition at @eccvconf our Beyond Euclidean workshop is back, now at @ICCVConference in October! We will update our webpage (sites.google.com/view/beyond…) with information on our keynote speakers and open a call for full and short papers in the coming days!

Beyond Euclidean

Bringing together researchers to uncover the principles of Non-euclidean representations. Within deep learning, Euclidean geometry is the default basis for deep neural networks. The naive assumption...

Reconstructing 3D human-object interactions from images/videos is a key step towards realistic #3D humans for #AR/#VR and assistive #robots/#AI. To tackle this challenging problem my team and I have received an ERC Starting Grant 🎉 #ERCStG 📢 We look for 3x #PhD candidates! We highly value a strong programming and mathematical background in candidates, along with a strong creativity, curiosity, self-motivation and team spirit! We offer an exciting opportunity to conduct internationally visible #research in the stimulating environment of the University of Amsterdam (@UvA_Amsterdam, @UvA_Science, @Ellis_Amsterdam) along with a strong network of international collaborators, with a competitive compensation, while working in the brand new Lab42 building and living in one of the world’s most lively and liveable cities! The goal is performing cutting-edge fundamental research, publishing at top-tier venues, releasing data and code for the community, and introducing new research problems. If you are attending #ECCV2024 and have questions, I am happy to discuss with you at MiCo! (plz ping me via email) 🆘 Application deadline: Oct 31 🆘 CEST timezone 👉👉 We accept applications only through the portal below (includes a general description, application requirements, and employment conditions & benefits: vacatures.uva.nl/UvA/job/PhD… As a closing remark, a big thanks to @ERC_Research, all reviewers and panel members, as well as to all collaborators that contributed along the years for this exciting opportunity to arise! 🙏
