LLM Alignment as Retriever Optimization: An Information Retrieval Perspective arxiv.org/abs/2502.03699 We introduce a comprehensive framework that connects LLM alignment techniques with the established IR principles, providing a new perspective on LLM alignment.

I'm honored to be named to “AI's 10 to Watch” by IEEE Intelligent Systems for our research on Trustworthy NLP and Vision-Language Models. This biennial award recognizes 10 researchers who have made impactful scientific contributions to AI within 10 years of earning their PhD.

I know internship hunting has been especially tough this year -- I hear you! 📢Great news: Our team at Microsoft Research (Microsoft Research) has opened up a few additional internship slots for this summer! We're seeking talented PhD candidates with experience in 🖼️Multimodality,

🚀 Excited to share MetaScale, our latest work advancing LLM reasoning capabilities! MetaScale empowers GPT-4o to match or even surpass frontier reasoning models like o1, Claude-3.5-Sonnet, and o1-mini on the challenging Arena-Hard benchmark (lmarena.ai). Additionally, MetaScale

🚨 New paper 🚨 Excited to share my first paper w/ my PhD students!! We find that advanced LLM capabilities conferred by instruction or alignment tuning (e.g., SFT, RLHF, DPO, GRPO) can be encoded into model diff vectors (à la task vectors) and transferred across model

When answering queries with multiple answers (e.g., listing cities of a country), how do LMs simultaneously recall knowledge and avoid repeating themselves? 🚀 Excited to share our latest work with Robin Jia! We uncover a promote-then-suppress mechanism: LMs first recall all

🤖 Imagine a world where everyone has a personalized LLM agent by their side! Our latest research (arxiv.org/abs/2502.12149) explores how persona dynamics influence multi-agent competitive auctions. 🏆 Discover who wins, who loses, and the impact of personas on competitiveness!

Worried about backdoors in LLMs? 🌟 Check out our #NAACL2025 work on test-time backdoor mitigation! ✅ Black-box 📦 ✅ Plug-and-play 🛡️ We explore: → Defensive Demonstrations 🧪 → Self-generated Prefixes 🧩 → Self-refinement ✍️ 📄 arxiv.org/abs/2311.09763 🧵[1/n]

📢 Research internship Google📢 I am looking for a PhD student researcher to work with me and my colleagues on advanced reasoning and/or RAG factuality this summer Google Mountain View, CA. We will focus on open-source models and benchmarks, and aim to publish our findings.

Curious how LLMs tackle planning tasks, such as travel and computer use? Our new survey #PlanGenLLMs (arxiv.org/abs/2502.11221) builds on classic work by Kartam and Wilkins (1990) and examines 6 key metrics to compare today's top planning systems. Your next agentic workflow

#ICLR2025 Oral LLMs often struggle with reliable and consistent decisions under uncertainty 😵‍💫 — largely because they can't reliably estimate the probability of each choice. We propose BIRD 🐦, a framework that significantly enhances LLM decision making under uncertainty. BIRD
