New research out now! 🍔🏫 We mapped food outlets around schools in regional & metro Australia using Google Street View, finding that unhealthful options have dominated for 17 years. Time for action to promote healthier environments for adolescents! 👇 onlinelibrary.wiley.com/doi/full/10.10…

A Johns Hopkins University study found that measuring 162 quality metrics cost >$5 mil. Our team at UC San Diego Health, led by Drs. Aaron Boussina and Shamim Nemati, found that LLMs are a great way to scale quality measurement - needed for a learning health system. Paper: ai.nejm.org/stoken/default…

Really interesting paper from Carol El-Hayek on an iterative ML approach in EHR data. We try to find people who inject drugs when the standard rules only find a biased subset and we don't have enough information about nearly everyone else nature.com/articles/s4174…

1/ I'll be at #NeurIPS2024 presenting our work SmallToLarge (S2L): Data-efficient Fine-tuning of LLMs! 🚀 What’s S2L? It’s a scalable data selection method that trains a small proxy model to guide fine-tuning for larger models, reducing costs while preserving performance. 👇

📢📜 Excited to share that our paper "On the conversational persuasiveness of GPT-4" has been published in Nature Human Behaviour! 🤖 Key takeaway: LLMs can already reach superhuman persuasiveness, especially when given access to personalized information nature.com/articles/s4156…

We focus so much on what genAI can do. This paper asks what users can make them do. Steerability -- how easily users can guide a model to produce what they want, is a missing dimension in genAI evaluation, and this paper shows how to measure it. arxiv.org/abs/2503.17482

At MESH Incubator™ at Mass General Brigham 2025, Harvard Medical School’s Isaac Kohane shared a striking case: GPT-4 recommended treatment to a patient when assessing from the perspective of a doctor—but denied treatment as an insurer. Same patient, same facts, different values. #Harvard harvardmagazine.com/2025/05/harvar…
