Rumor has it Mother Nature might be the best AI engineer🌱💡 Come see why at Brass Bear Brewing, Nov 13 @ 6pm. With Dr. Fatih Dinc, we’ll dive into how brains, bots, and biology compute with intelligence

Congratulations, @SMataigne !

The second paper called "On the Approximation of the Riemannian Barycenter" uses the bounds from the above article to compute approximations of the Riemannian barycenter at very low computational cost! https://t.co/ARw2prN8vK

The first paper called "Bounds on the geodesic distances on the Stiefel manifold for a family of Riemannian metrics" studies the geometry of the Stiefel manifold to derive simple and insightful bounds on the computationally untractable geodesic distance. https://t.co/xWwD0pkVAf

Thrilled to see these two papers by @SMataigne co-authored with P.-A. Absil published this month 🤩 They connect deep mathematical theory to practical algorithms on the Stiefel manifold and the approximation of the Riemannian barycenter 🌐 Details & papers👇@geometric_intel

Interested in Topological Deep Learning?🍩 20 days is more than enough to participate in the Topological Deep Learning challenge 2025! Details (including prizes) below 🌟 @geometric_intel @UCSBengineering @ucsantabarbara @EPFL @mathildepapillo @gbg1441 @lev_telyatnikov

This is the final 20-day countdown! Our step-by-step tutorial makes it easy to get started, especially for dataset contributions (Mission A), which can be added in just a couple of hours. Check the tutorial and submit your work:

Do you have ideas for new tasks within TDL? Or a completely new challenge of your own? Then Mission B, Category B.2 is for you: Pioneering New TDL Benchmark Tasks! We want to see your most creative and impactful ideas.

Are you interested in large-scale Topological Deep Learning? We are too! That's why Mission B, Category B.1 is focused on Advancing the Data Infrastructure. This is your chance to make TDL more scalable and robust.

"But I don't have a novel dataset!" No problem! Mission A is all about growing the TopoBench ecosystem. Datasets are NOT required to be novel. If you have topological data, make it available within TopoBench to compete. It's that simple!

Beyond the prizes, these internships offer a perfect opportunity to initiate collaboration with top-tier labs at @UCSB and @EPFL. Whether you're a Master's or PhD student, this challenge is your chance to gain visibility, make an impact, and connect with strong research groups.

As a reminder, we have incredible prizes for winners, graciously offered by our partners: 💰 Win cash prizes up to $800 USD from #ArlequinAI 🎓 Secure prestigious internships: @UCSB (for PhD students)  @EPFL (for Master's students)

🚨 20 DAYS LEFT to submit to the Topological Deep Learning Challenge! TopoBench just hit 200 stars 🌟, and we're looking forward to seeing your submissions before the deadline. This year's challenge has multiple ways to contribute and prizes. All details: https://t.co/JDRgKVmOAH

I am recruiting PhD students for 2026!😃 You want to reveal the geometric signatures of natural and artificial intelligence, and understand computations in brains and AI? 🌐🧠🤖 Apply to the UCSB Geometric Intelligence Lab ✨ This is the view you'd have from... your desk🌴

We are physicists, neuroscientists, mathematicians and computer scientists who study intelligence in biological and artificial neural networks and use our findings to build better AI models. 👉You can join us via the ECE, CS, Math or DYNS programs!

You are specifically interested in AI? 👉 Look at the AI Curriculum from the UCSB Real AI Initiative offered within the CS and the ECE departments. https://t.co/vFgctJUtwe @ai_ucsb @ucsbcs @ucsbece

From your desk you'll see dolphins, beach volleyball courts, a great surf spot, & more importantly: your passionate, kind, & smart colleagues. @gbg1441 @hopfbifurcator @helloyesimsarah @AdeleMyersPhD @louisacornelis @AbbyBertics @mathildepapillo Luis Pereira Alex West

Details on our research and how to apply to our lab are on our website: https://t.co/LfCXn07g4b. We hope to hear from you! 👋 @UofCalifornia @ucsantabarbara @ucsbece @ucsbcs @geometric_intel

Once again, let’s push the boundaries of TDL together! Can’t wait to see our community grow 🚀 #TDLChallenge2025 #ML #AI

Big thanks to our amazing partners for making this possible: 🙏 @TAGinDS for hosting 💡 Arlequin AI for sponsoring 🎓 @geometric_intel & IMOS labs for offering internship opportunities
