A Computational Framework for Behavioral Assessment of LLM Therapists

1 code implementation1 Jan 2024 Yu Ying Chiu, ASHISH SHARMA, Inna Wanyin Lin, Tim Althoff

Subsequently, we compare the behavior of LLM therapists against that of high- and low-quality human therapy, and study how their behavior can be modulated to better reflect behaviors observed in high-quality therapy.

Investigating Agency of LLMs in Human-AI Collaboration Tasks

no code implementations22 May 2023 ASHISH SHARMA, Sudha Rao, Chris Brockett, Akanksha Malhotra, Nebojsa Jojic, Bill Dolan

While LLMs are being developed to simulate human behavior and serve as human-like agents, little attention has been given to the Agency that these models should possess in order to proactively manage the direction of interaction and collaboration.

Gendered Mental Health Stigma in Masked Language Models

no code implementations27 Oct 2022 Inna Wanyin Lin, Lucille Njoo, Anjalie Field, ASHISH SHARMA, Katharina Reinecke, Tim Althoff, Yulia Tsvetkov

Mental health stigma prevents many individuals from receiving the appropriate care, and social psychology studies have shown that mental health tends to be overlooked in men.

Human-AI Collaboration Enables More Empathic Conversations in Text-based Peer-to-Peer Mental Health Support

no code implementations28 Mar 2022 ASHISH SHARMA, Inna W. Lin, Adam S. Miner, David C. Atkins, Tim Althoff

Advances in artificial intelligence (AI) are enabling systems that augment and collaborate with humans to perform simple, mechanistic tasks like scheduling meetings and grammar-checking text.
