Can LLMs support behavioral health documentation without compromising quality? Our ACL 2025 paper introduces TN-Eval: a comprehensive framework for evaluating therapy notes, co-designed with 22 licensed therapists. Key finding: In blind tests, therapists rated LLM-generated

This aligns with the growing trend β€” echoed by efforts like OpenAI's #HealthBench β€” of using structured criteria to guide and evaluate LLM applications in clinical settings.

In this work, we propose detailed rubrics tailored to the behavioral health domain and show that rubric-based evaluations offer significantly more reliability than standard Likert-scale ratings.

Really excited to announce that our NeurIPS 2019 paper on 'Modeling tabular data using conditional GAN' has surpassed 1k citations! It's inspiring to see researchers applying the model innovatively in the era of LLMs. #NeurIPS #GAN #SyntheticData #MIT

MIT machine learning just got a whole lot stronger with new hires Pulkit Agrawal (@pulkitology), Jacob Andreas (@jacobandreas) and Cathy Wu (@wucathy). All starting in Fall 2019. All coming from my alma mater UC Berkeley :)
