Michelle Bak, a doctoral pupil in info sciences, and Professor Jessie Chin lately revealed their findings within the Journal of the American Medical Informatics Affiliation. Their examine aimed to find out whether or not massive language fashions may successfully establish customers’ motivational states and supply applicable info to assist their journey in the direction of more healthy habits.

Examine Design

To evaluate the capabilities of massive language fashions in selling conduct change, Bak and Chin designed a complete examine involving three outstanding chatbot fashions: ChatGPT, Google Bard, and Llama 2.
