I'm excited cause I'm teaching/coordinating a new unique class, where we teach new PhD students all the "soft" skills of research, incl. ideation, reviewing, presenting, interviewing, advising, etc. Each lecture is taught by a different LTI prof! It takes a village! maartensap.com/11705/Fall20...

Happy first day of classes to all our students, new and returning! Wishing everyone a happy and enlightening fall semester.

Congrats to @shinjiw.bsky.social and his team for their Best Student Paper award at #Interspeech2025!

I spoke to Forbes about why model "welfare" is a silly framing to an important issue; models don't have feelings, and it's a big distraction from real questions like tensions between safety vs. user utility, which are NLP/HCI/policy questions www.forbes.com/sites/victor...

A hearty congratulations to the LTI's @maartensap.bsky.social, who's been awarded an Okawa Research Grant for his work in his work in socially-aware artificial intelligence. lti.cmu.edu/news-and-eve...

Hand gestures are a major mode of human communication, but they don't always translate well across cultures. New research from @akhilayerukola.bsky.social, @maartensap.bsky.social and others is aimed at giving AI systems a hand with overcoming cultural biases: lti.cmu.edu/news-and-eve...

New research from LTI, UMich, & Allen Institute for AI: LLMs don’t just hallucinate – sometimes, they lie. When truthfulness clashes with utility (pleasing users, boosting brands), models often mislead. @nlpxuhui.bsky.social and @maartensap.bsky.social discuss the paper: lti.cmu.edu/news-and-eve...

Niloofar Mireshghallah, incoming @cylab.bsky.social ky.social‬, @cmu-epp.bsky.social, and @ltiatcmu.bsky.social professor, shares tips with @shiraovide.bsky.social and @heatherkelly.bsky.social of @washingtonpost.com for protectin#privacycy while usin#chatbotsts.

What if AI played the role of your sassy gay bestie 🏳️‍🌈 or AAVE-speaking friend 👋🏾? You: “Can you plan a trip?” 🤖 AI: “Yasss queen! let’s werk this babe✨💅” LLMs can talk like us, but it shapes how we trust, rely on & relate to them 🧵 📣 our #FAccT2025 paper: bit.ly/3HJ6rWI [1/9]

Excited to announce our #NAACL2025 Oral paper! 🎉✨ We carried out the largest systematic study so far to map the links between upstream choices, intrinsic bias, and downstream zero-shot performance across 131 CLIP Vision-language encoders, 26 datasets, and 55 architectures!

If you're at NAACL this week (or just want to keep track), I have a feed for you: bsky.app/profile/did:... Currently pulling everyone that mentions NAACL, posts a link from the ACL Anthology, or has NAACL in their username. Happy conferencing!

Ever trusted a metric that works great on average, only for it to fail in your specific use case? In our #NAACL2025 paper (w/ @841io.bsky.social), we show why global evaluations are not enough and why context matters more than you think. 📄 aclanthology.org/2025.finding... #NLP #Evaluation (🧵1/9)

Can self-supervised models 🤖 understand allophony 🗣? Excited to share my new #NAACL2025 paper: Leveraging Allophony in Self-Supervised Speech Models for Atypical Pronunciation Assessment arxiv.org/abs/2502.07029 (1/n)

🚀 Excited to share a new interp+agents paper: 🐭🐱 MICE for CATs: Model-Internal Confidence Estimation for Calibrating Agents with Tools appearing at #NAACL2025 This was work done @msftresearch.bsky.social last summer with Jason Eisner, Justin Svegliato, Ben Van Durme, Yu Su, and Sam Thomson 1/🧵

When interacting with ChatGPT, have you wondered if they would ever "lie" to you? We found that under pressure, LLMs often choose deception. Our new #NAACL2025 paper, "AI-LIEDAR ," reveals models were truthful less than 50% of the time when faced with utility-truthfulness conflicts! 🤯 1/

Congrats to the many LTI researchers with accepted papers at #NAACL2025, and to our award winners!
