@xwang_lk @CtrlAltDwayne Better to limit by first author. Otherwise, it would be squid game for phd students.

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 notes as superior to human-written ones! 🤔

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

@ErikSchluntz Love this! The sound is super calming.

@MIT_CSAIL Time flies. Skype was probably the only option when I was applying for PhD.

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

What??? (IMO 2022, Chinese team)

I’m attending NAACL at Seattle. Happy to grad ☕️ 🍺 and chat. #NAACL2022

Researchers w/ MIT's Laboratory for Information & Decision Systems in the College of Computing released the Synthetic Data Vault — a one-stop shop where users can get as much data as they need for their projects, without compromising privacy.

What do CSAILers think of programming?

[MIT CSAIL @MIT_CSAIL]

Describe programming in only six words.

We'll RT all the best ones.

[Lei Xu @XuLeonard]

@MIT_CSAIL I can fix that very quick.
