The first draft 'G' chapter of the geometric deep learning book is live! 🚀 Alice enters the magical, branchy world of Graphs and GNNs 🕸️ (LLMs are there too!) I've spent 7+ years studying, researching & talking about graphs -- This text is my best attempt at conveying everything i've learnt 💎

The recording of my 'LLMs as GNNs' talk is now public (link in thread) 💬🕸️ Thank you to everyone in the GLOW community for having me -- I had a fantastic time! 🌟 (And I look forward to refining this content even further -- especially as new works come trickling in 👀)

This is happening today! 🌟 Join me at the virtual GLOW seminar (5pm CET) for the first public showing of my 'LLMs as GNNs' talk. 💬🕸️

GLOW is returning on 𝗠𝗮𝗿𝗰𝗵 𝟮𝟲𝘁𝗵, 𝟱𝗽𝗺 𝗖𝗘𝗧 with a special guest: @petar-v.bsky.social 🌟 He will lecture on LLMs as GNNs – a topic which received quite some attention at our last session. Specifically, we will learn how Graph ML tools can help understand LLM generalisation

I'm excited to share that we'll have Ilan Price giving a talk at the University of Cambridge on GenCast -- a state-of-the-art model for probabilistic weather forecasting 🌦️⛈️⛅️ If you're in Cambridge next Wednesday (19 Feb), consider joining us -- it's open to all! All details (+ Zoom link) below!

And so we set out to understand _feedforward_ graphs (i.e. graphs w/o back edges) ⏩ Turns out these graphs are rather understudied for how often they are used in practice! 😮 We work towards a framework to analyse them, which I hope both my GNN and my LLM friends will enjoy 🚀

This summer, a group of elite AI scientists and engineers will come over to Sarajevo 🇧🇦 for #EEML2025 ❤️ We've been working hard behind the scenes to prepare a stellar program for our attendees! Trust me, you don't want to miss this 🚀 Applications open now! (details in post)

EEML@eemlcommunity.bsky.social · last yr.

Applications are now open for EEML 2025 in Sarajevo, Bosnia and Herzegovina, 21-26 July! 🎉 Learn from top AI researchers and connect with peers in Sarajevo 🇧🇦, a historical crossroads of East and West. Needs-based scholarships are available. Deadline: 31 March 2025.

Exciting news: the NeurIPS Sci4DL Workshop has recognised our softmax paper as a best paper runner-up for its 'Debunking Challenge'! 🚀🧑‍🔬 I'm really grateful to Christos and Federico for tirelessly presenting our work throughout the day, and to all attendees who kindly stopped by our talks/posters! 🙌

It's official! 🎉 I am excited to share that EEML will be coming to Sarajevo 🇧🇦 next summer! For those not familiar, EEML is the flagship AI summer school for the Eastern European region (and beyond!). Watch this space! More information on how to apply, lecturers, etc... is coming soon 👀

EEML@eemlcommunity.bsky.social · 2y ago

EEML'25, our yearly machine learning summer school event, will be organised next summer in the beautiful city of Sarajevo - the place where East meets West 🇧🇦🇧🇦🇧🇦. More details coming soon, please see the link in the thread!

Today it is time to present our softmax paper to the world! 🌡️ If you're at #NeurIPS2024 today, check out our two Workshop spotlights 🔦 🧑‍🔬 Sci4DL (by Christos Perivolaropoulos), West Meeting Rooms 205-207, 10:50--11:05am 🔢 System II (by Federico Barbero), West Ballroom B, 9:20--9:30am

Just a poster I'm very proud of. Mainly because it's the first time I led a theory-focused paper 🥳 Coming soon to NeurIPS Workshops near you (two spotlights!!) 🔦 I unfortunately won't be there myself, but Christos and Federico will be around 🚀

A very nice blog from Przemek Pietrzkiewicz, offering thoughts on our recent result in AI for competitive programming 🏆 Przemek co-led the Hash Code contest, which we used as the main test-bed to evaluate our approach 🚀 Worth a read if you want to understand implications of our work! Link below ⬇️

Our team at Google DeepMind is hiring Student Researchers for 2025! 🧑‍🔬 Interested in understanding reasoning capabilities of neural networks from first principles? 🧑‍🎓 Currently studying for a BS/MS/PhD? 🧑‍💻 Have solid engineering and research skills? 🌟 We want to hear from you! Details in thread.

Introducing 🧞Genie 2 🧞 - our most capable large-scale foundation world model, which can generate a diverse array of consistent worlds, playable for up to a minute. We believe Genie 2 could unlock the next wave of capabilities for embodied agents 🧠.

A clear step towards achieving my dream: building AI that assists competitive programmers 🧑‍💻 “This is an exciting approach to combine work of human competitive programmers and LLMs, to achieve results that neither would achieve on their own.” --Petr Mitrichev More details below! 🧵

The key productivity hack I unlocked in recent years was accepting and being cognisant of the fact that I likely won't finish everything I was planning to do at the start of the day. 😶 Ironically, this led to ~2x more things being finished, because I spend less time worrying about falling behind 🥳

✨EXCITING NEWS! We now have a Bluesky account!! AND registration for the 3rd Learning on Graphs conference is open 😊 It is virtual, free to attend, livestreamed, and recorded 📹 Sign up today! The conference is this coming week 😱 forms.gle/eYiDCopJGUc8...

As an example from our recent paper, turns out that assuming a _tokenised vocabulary_ input allows one to apply mathematical analysis results due to Weierstrass, which in turn implies that all sharp attention heads must collapse. Crazy chain of thought, and not at all what we expected at the start.

My fav theoretical proofs in AI papers tend to be ones that make assumptions that: * realistically conform to the 'situation on the ground', i.e. ~match models used in practice; * completely catch you off-guard, i.e. you see the assumption and you have no upfront idea what issue it will help patch.
