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.

Facilitating Self-Guided Mental Health Interventions Through Human-Language Model Interaction: A Case Study of Cognitive Restructuring

no code implementations24 Oct 2023 ASHISH SHARMA, Kevin Rushton, Inna Wanyin Lin, Theresa Nguyen, Tim Althoff

In an IRB-approved randomized field study on a large mental health website with 15, 531 participants, we design and evaluate a system that uses language models to support people through various steps of cognitive restructuring.
