🚨 Paper Alert: “RL Finetunes Small Subnetworks in Large Language Models” From DeepSeek V3 Base to DeepSeek R1 Zero, a whopping 86% of parameters were NOT updated during RL training 😮😮 And this isn’t a one-off. The pattern holds across RL algorithms and models. 🧵A Deep Dive

🚀Our ICML 2025 paper introduces "Premise-Augmented Reasoning Chains" - a structured approach to induce explicit dependencies in reasoning chains. By revealing the dependencies within chains, we significantly improve how LLM reasoning can be verified. 🧵[1/n]

AI over-reliance is an important issue for conversational agents. Our work supported mainly by the DARPA FACT program proposes introducing positive friction to encourage users to think critically when making decisions. Great team-work, all! @convai-uiuc.bsky.social @gokhantur.bsky.social

I noticed a lot of starter packs skewed towards faculty/industry, so I made one of just NLP & ML students: go.bsky.app/vju2ux Students do different research, go on the job market, and recruit other students. Ping me and I'll add you!

📢📢LLMs are biased towards Western Culture. Well, okay, but what do you mean by "Culture"? In our survey of on cultural bias in LLMs, we reviewed ~90 papers. Interestingly, none of these papers define "culture" explicitly. They use “proxies”. [1/7] [Appeared in EMNLP mains]

Nice overview of the ReSpAct framework for conversational task completion agents @convai-uiuc.bsky.social cobusgreyling.medium.com/building-con...

There! I went for it! (Let me know everyone if you want me to add or remove you) go.bsky.app/CUuio7g

Welcome to the official page of ConvAI@UIUC! 🤖 Based in the cornfields of UIUC, and led by Dilek Hakkani-Tur and Gokhan Tur, we do cool research on chatbots, dialogue, embodied agents, and everything in between!

We had so much fun at #EMNLP2024 during the poster sessions and in Miami 🎉🎉 Evidence of fun (excursion to the south beach! 🏖️):
