🧵 (oh god my first post) Excited to present at ICWSM 2025! In this paper with 🇺🇦 Kristina Lerman 🇺🇦 we introduce a novel framework for modeling narrative evolution in streaming text data.

Why Care? Traditional approaches provide snapshots; our method captures the process itself. 93.2% of trending clusters correspond to documented external events, validating our temporal detection capabilities. Paper (code linked there) here: arxiv.org/abs/2409.07684

🧵ALSO Excited to present our work on "othering" at ICWSM 2025! In this paper with 🇺🇦 Kristina Lerman 🇺🇦 and Tim Weninger, we go beyond traditional (hate|fear) speech to identify and study the process of depicting outgroups as fundamentally different.

🧵 While I'm here, I ought to post about my newest work with Hans Hanley, Luca Luceri, and Emilio Ferrara, in which we build out a new cross-platform/platform-agnostic framework for creating user networks.

This is a new way of thinking about user networks: birds of the same feather don't simply tweet together; they *think* together. Connecting users via latent narratives lets us model with less data and break from arbitrary platform boundaries. Paper here: arxiv.org/abs/2505.21729

Go check out Patrick Gerard's work at ICWSM 2025 in Copenhagen!! Really a rising star in computational social science!

Honored to receive the Google Scholar Research Award for my proposal, “A New Generation of AI-Powered Population Health Models”! We aim to build rich, multimodal models that unite behavioral, disease & policy data to holistically model population dynamics, health & interventions

LLMs will NEVER truly reason, because reasoning must be self-consistent, yet LLMs are made out of MATH and thus CANNOT be self-consistent

I’ve joined AIX Ventures as a General Partner, working on investing in deep AI startups. Looking forward to working with founders on solving hard problems in AI and seeing products come out of that!  Thank you Yuliya Chernova at The Wall Street Journal for covering the news: wsj.com/articles/ai-re…

🎉 Excited to announce that the 4th HCI+NLP workshop will be co-located with @EMNLP in Suzhou, China! 🌍📍 Join us to explore the intersection of human-computer interaction and NLP. 🧵 1/

Funding John's lab or just getting coffee with him probably an S-tier move

when i first learned Machine Learning, our professor ingrained into us how every ML problem starts by splitting data into train, test, and validation these days there is just train and test. in many cases there is just train and more train where’d all the validation sets go?

Today we launched a new product called ChatGPT Agent. Agent represents a new level of capability for AI systems and can accomplish some remarkable, complex tasks for you using its own computer. It combines the spirit of Deep Research and Operator, but is more powerful than that

Kimi K2. More evidence that: • The lead of American “frontier” AI companies is rather small 🔬 • A broad ecosystem of strong foundation model companies is developing in China, with more players than in the US or elsewhere. 🐅 moonshotai.github.io/Kimi-K2/ github.com/MoonshotAI/Kim…

📢The ACL 2025 Proceedings are LIVE🎆on the ACL Anthology! 🎉 We're thrilled to pre-celebrate the incredible research that will be presented starting Monday, July 28th, in Vienna! 🇦🇹 Start exploring now▶️aclanthology.org/events/acl-202… #NLProc #ACL2025NLP #ACLAnthology 📚

I don't know if I can acknowledge this. Irregardless, I think I must

I am very excited to take up the role of chief scientist for meta super-intelligence labs. Looking forward to building asi and aligning it to empower people with the amazing team here. Let’s build!

Headed to Vienna! Oddly enough on the way over they were selling cigarettes on the plane-- even had the attendants do a full lap just with them--which is a choice...
