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 💎
petar-v.bsky.social
...but our model regressed on Quickselect rather than improving it, so I'm indeed curious to explore what you've done differently :)
petar-v.bsky.social
Cool stuff! Will give it a read.

We also built a 'fully tropical' GNN following similar principles a few years back (from
the perspective of asynchrony invariance), might be a good reference:

I would say it definitely does! The book does rely on theoretical material but is designed to be a self-contained, deep learning-oriented introduction to those topics.

So if you read the chapters in sequence it _should_ be just fine :)

(would appreciate any feedback if you do try it!)

4yrs ago, the Geometric Deep Learning proto-book hit the arXiv 📚

Today, we proudly release *Chapter 4* of the GDL Book! 📖 Wrapping up foundations, exceeding the proto-book page count 🚀

Next: deep-dives into the 5 Gs! #⃣🔁🕸️🌐🪢

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 👀)
petar-v.bsky.social
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!

It's been great working on this with Alex, @joao.omg.lol and Marc on this over the past couple of months!

We don't believe we solved the problems studied here -- mainly brought them to attention -- and we welcome any and all comments!

Read our work on the arXiv:

What makes a good feedforward computational graph?
As implied by the plethora of literature on graph rewiring, the choice of computational graph employed by a neural network can make a significant impact on its downstream performance. Certain effects ...

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 🚀

*Round and Round We Go! What makes Rotary Positional Encodings useful?*

by @petar-v.bsky.social et al.

They show RoPE has distinct behavior for different rotation angles - high freq for position, low freq for semantics.

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'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
petar-v.bsky.social
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 ⬇️
