Knowledge Graph Foundation Models (KGFMs) are at the frontier of graph learning - but we didn’t have a principled understanding of what we can (or can’t) do with them. Now we do! 💡🚀 🧵 with Pablo Barcelo, @ismaililkanc, @mmbronstein, @michael_galkin, @JuanLReutter, @OrthMiguel

@RoryStewartUK @jfwduffield To be fair, it is only in the United States where they can become VP of the United States 🙂

Rory Stewart@RoryStewartUK·23 Oca

This “only in America can a hardworking person rise to be a politician” is a noxious myth. In reality US politics is more dominated by money and privilege than any democracy on earth. Countries like Britain have had many more examples as @jfwduffield says - Ramsay MacDonald , John Major. David Blunkett, David Davis, Angela Rayner and another 50 current MPs

Speaker Mike Johnson@SpeakerJohnson

As we gathered for our meeting at the White House yesterday, JD Vance mentioned to us that he had never before visited the Oval Office. I told him and President Trump that I HAD to capture the moment on video. Only in America can a hardworking young man from Appalachia rise from his humble circumstances to enter the Oval for first time as VICE PRESIDENT OF THE UNITED STATES. What a country! 🇺🇸

⭐️LOGML is back and we are looking for mentors!⭐️ Do you work in geometry or machine learning? Apply by February 16th! Mentors lead a group of 6 students to work on a project during the week and some groups end up publishing their work. More information at logml.ai

LOGML Summer School@LogmlSchool

⭐️Mentor applications open⭐️ We're excited to announce that LOGML summer school will return in London: July 7-11 2025. We are seeking mentors to lead group projects at the intersection of geometry and machine learning. Find out more and apply: logml.ai

@jonkhler The reasoning I have seen is that the end of life on earth is inevitable so we should work towards colonizing space in some super long time horizon (blah blah longtermism). Using this as a way to detract from current problems and extending life on earth is bizarre to me...

Why is everyone on this app so excited about space travel/colonization? It makes no sense. Happy to hear why it should :) My uninformed take: Traveling even to the closest stars is beyond anything feasible and would require tens to hundreds of thousands of years. 1/

@aidangomez why not work on problems with global impact with the top global talent, anywhere in the world?

Every British computer scientist should be working for Cohere, Wayve, Monzo, Deliveroo, GCHQ, or starting a company for the home that raised them.

@avishvj @rballeba Yeah this is super cool!

English

Avish Vijayaraghavan@avishvj·27 Ara

@JoshSouthern13 @rballeba this was a collab w a big club but might be doable with smaller clubs for lower fees? public data may work too but it would be a ton of noisy video data (which requires conversion to graphs)

English

Rubén Ballester@rballeba·27 Ara

I think there is enough theory to build a startup on fundamental models for graph domains. We have powerful graph transformers (even equivariant), a robust literature on positional encodings, challenging graph problems...

@rballeba @miniapeur @primetrip345 Potentially, don't know much about KGs tbh - would need some convincing why structured data is more useful than text + LLMs

English

Rubén Ballester@rballeba·27 Ara

@JoshSouthern13 @miniapeur @primetrip345 What do you think of embeddings of knowledge graphs/knowledge graphs generation from text/images? I think this could be very useful for big companies as well

English

Josh Southern@JoshSouthern13·27 Ara

@rballeba @miniapeur @primetrip345 Yeah I see this as a problem where graphs would work well. I also like the business model of Kumo AI where they build general models for relational databases

@miniapeur @rballeba Yes exactly, you're completely reliant on data sharing or an acquisition by one of said companies

Mathieu@miniapeur·27 Ara

@rballeba @JoshSouthern13 But how can we develop methods on social networks (Facebook, Twitter, etc.) if we don’t have access to them?

Josh Southern@JoshSouthern13·27 Ara

@rballeba Drug discovery is getting massively funded but not sure tackling it with 'fundamental' graph research is the way forward. Agree with social networks but not sure of the future of this after the graph twitter team... Sport is interesting! Do you have any material on this?

English

Rubén Ballester@rballeba·27 Ara

@JoshSouthern13 Also maybe sports, I feel like pose graphs are better suited for helping teams to analyze strategies in most sports than pure videos/images.
