Purkayastha receives NSF grant to study benefits of AI and radiologist co-learning

November 7, 2019

Biohealth informatics Assistant Professor Saptarshi Purkayastha of the School of Informatics and Computing has received a $826,795 grant from the National Science Foundation, entitled “FW-HTF-RM: Measuring learning gains in man-machine assemblage when augmenting radiology work with artificial intelligence.”

Purkayastha is the principal investigator with co-PIs Elizabeth Krupinski of Emory University, Joshua Danish of the IU School of Education, and Judy Gichoya, M.D., formerly of Indiana University. Gichoya received her M.S. in health informatics from the School of Informatics and Computing and M.D. in radiology from IU School of Medicine before receiving a fellowship at the Dotter Department of Interventional Radiology at Oregon Health and Science University.

The three-year grant will look at artificial intelligence (AI) in a unique and novel way: as part of a man-machine assemblage. In the past, these would have been trained as separate entities—much like a self-driving car and driver—rather than learning and training together at the same time.

“We want to enable the synergy in a way that it does no patient harm and reduces burden on radiologists.”

The group has recruited 36 radiologists, ranging from first-year resident to highly experienced, and will conduct the study at Emory. Purkayastha will perform the Electronic Health Record software tooling and Danish will evaluate the learning. Participants will view over 1600 images over two 6-month phases, and gains on tasks will be measured for groups with and without the assemblage training.

One of the top priorities at the NSF is to discover how human work will change with the introduction of AI. The results of this study may point to how people and AI can work better on any cognitive task when they are treated as one unit. “Most people believe that the future of radiology work will be augmented with artificial intelligence in some way, but we want to enable the synergy in a way that it does no patient harm and reduces burden on radiologists,” says Purkayastha.
