A new study conducted by PhD student Michelle Bak and Assistant Professor Jessie Chin, which was recently published in the Journal of the American Medical Informatics Association (JAMIA), reveals how large language models (LLMs) respond to different motivational states. In their evaluation of three LLM-based generative conversational agents (GAs)—ChatGPT, Google Bard, and Llama 2—the researchers found that while GAs are able to identify users' motivation states and provide relevant information when individuals have established goals, they are less likely to provide guidance when the users are hesitant or ambivalent about changing their behavior.

A new study by PhD student Kyrie Zhixuan Zhou and Assistant Professor Madelyn Rose Sanfilippo has uncovered the existence of gender bias in Large Language Models (LLMs) in the U.S. and China. The researchers examined public discussion about this topic on the social media platforms Twitter (now X) and Weibo, finding reports of gender bias in the LLMs ChatGPT and Ernie, China's ChatGPT-equivalent.

There are approximately 600,000 individuals in the U.S. who are undergoing hemodialysis (HD) therapy for kidney failure. In hemodialysis, a machine filters wastes, salts, and fluid from the blood when an individual's kidneys are no longer healthy enough to do this work adequately. While lifestyle changes such as getting more exercise and making better nutritional choices would benefit HD patients, they are not popular with patients—leading to poor health outcomes. A new project, led by Assistant Professor Jessie Chin, aims to boost HD patients' commitment to exercise through a long-term motivational interviewing conversational agent (LotMintBot).

In July 2020, Chancellor Robert J. Jones announced the creation of the Call to Action Research Program to Address Racism and Social Injustice, a $2 million annual commitment by the University of Illinois to respond to the critical need for universities across the nation to prioritize research focused on systemic racial inequities and injustices that exist not only in communities but in higher education itself. On November 2, Chancellor Jones announced that 22 projects have been funded through this new program. Associate Professor Anita Say Chan will serve as a lead on two projects.

In the event of a natural disaster like Hurricane Ida, artificial intelligence (AI) may be used to assess damage, using imagery reports to identify the severity of flooded areas. Using AI in disaster scene assessment has its limitations, however, and input from the people affected is needed, in order to get a better picture. A new project being led by Associate Professor Dong Wang will explore the power of human intelligence to address the failures of existing AI schemes in disaster damage assessment applications and boost the performance of the system. Wang has received a three-year, $499,786 National Science Foundation (NSF) Human-Centered Computing (HCC) grant for his new project, "DeepCrowd: A Crowd-assisted Deep Learning-based Disaster Scene Assessment System with Active Human-AI Interactions."

While empathy is important in almost every aspect of daily life, it is not always a priority in the development of technology, especially technology using artificial intelligence (AI). iSchool researchers are working to address this gap by using empathy to teach high school students about cybersecurity and AI ethics issues.
