🎉New Preprint! 🎉 Shreya Shankar led this investigation of challenges in aligning LLM outputs: *people* don't always have clear criteria, and these "squishy" criteria also drift as users tweak prompts + evaluate outputs. Human input critical in guiding co-evolution of prompts & evals!


"Rambler", a tool developed by Susan Lin Jeremy Warner J.D. Zamfirescu et al. provide a tool that converts your spoken rambling into coherent, written text! The "semantic zoom" tool lets you slide through versions of Full, 50%, 25%, and 10% length. This is the #CHI2024 tool I most need...


This is really cool new feature we've been working on Can you automatically improve/build LLM evaluators based on observing human feedback? Now live in LangSmith! Inspired by a lot of Shreya Shankar's great work

autoblocks Our technique, which we're calling ALIGN... Automated LLM-as-a-judge Improvement Guided by Notable Feedback ...was heavily inspired by the work of Shreya Shankar, J.D. Zamfirescu, Bjoern Hartmann, Aditya Parameswaran, and Ian Arawjo in their paper: arxiv.org/pdf/2404.12272…




Paraphrasing from David Barstow's super motivating UC Berkeley EPIC Lab keynote: As computer scientists, "is the work you're doing supporting the world of truth? Or is it supporting the world of lies?"

Paper link: arxiv.org/abs/2404.12272 J.D. Zamfirescu and Ian Arawjo will also be around!!

Please retweet: I am recruiting PhD students at Berkeley! Please apply to UC Berkeley EECS or UC Joint Computational Precision Health Program if you are interested in ML applied to health, inequality, or social science, and mention my name in your app. More details on work/how to apply: cs.cornell.edu/~emmapierson/


📈Top cited articles from the last two years of ACM CHI (ACM CHI Conference) – the premier publication venue for HCI ("Human-Computer Interaction") research. What do you notice?


Tovi Grossman ACM CHI Conference I notice that J.D. Zamfirescu and Majeed Kazemitabaar are awesome.
